Not be beat a dead horse, but the poster of the image didn't say, "I wanted to make this look as real as possible." He/she posted a fantasy render using a physically based rendering engine. The fantasy is obvious from the subject matter and composition. Any criticism, should someone feel compelled, ought to be confined to addressing the intent of the art. Using Iray or any PBR doesn't mean only completely realistic subjects. Pixar makes animated cartoons with PBR renderers. No one complains Woody and his pals don't look real. PBRs are simply another way to make art. The intent of that art -- cartoonish, fantasy, Uncanny Valley real -- is up to the individual creator.
First of all, thanks for the praises. For me it is my best work yet and also feedback says same. But no reason for a rest:
To do it the right way for everyone is very difficult. At another site someone said that the car is looking to plastic. So in which direction I should change the image?
Best regards

There are several posts in this thread where members are asking for help and and advice, cesariuss_fa7fad02bd. I'm sure they would appreciate it if you shared your experience with them. Also there is this thread where Iray beginners are asking for tips and tricks:

@Tobor "down to the pink grips on her pistols. Is that real? Of course not! "
FWIW, plenty of pinks grips for virtually every pistol made. :)
Even Pink rifles and shotguns
There's no real "right way," and you should only change it if you feel it needs to be changed. Do it the way you see it in your head. To me, it's the car Killer Barbie would be driving.
If you're looking for something to do, you might try experimenting with the background, to put a little more action into it. But if it were me, I'd move on to the next work. Put this away for a while, then come back. You'll know if it needs anything else. Trust your instincts.
Yeah, that skin was just stupidly wrong, completely unrealistic, what were you even thinking?
Need to make it realistic like THIS:
(but seriously, I thought it was an awesome render)
Seems you work since aeons with IRAY.
Interesting rug Miss Wood is sitting on, but the background makes me a bit queasy and nervous. Where is she???
I thought it looked like internal tissue, like intestines or something. It definitely looks organic. It is an interesting image, for sure.
That's a very grainy image there...
Another fun thing to do is set the Metallicity slider to 1 on the skin surfaces, it kinds of looks like metallic body paint. There's also the Metallic Flakes settings in the Iray shader, haven't played around much with that one yet...
Personally I don't strive for photorealism in my renders so much as, avoiding uncanny valley. Leaving depth of field turned off on your camera along with the SSS haze trick, and adding some point spotlights here and there to illuminate key elements in the scene can make for some nice effects, making it look more like a painting than a photograph. And keep in mind, how a camera works is not the same as how the human eye works, and is not necessarily a higher standard of realism.
If I were director of Pixar or Disney I would never allow animators to do such unrealistic renders.
LOL.
Just joking.
Let it go.
Well, letting sarcasms apart its truly a realistic image. It looks like some kind of experimental sculpture in wood of a woman, even the golden hair looks cool, for not to talk about that bubble walls. One of the most original and interesting images Ive seen in so many time. (Seriously)
Aw, thanks. I've always been a fan of surrealism.
I don´t know how much time William haves but....Honestly... I had barely one week working with that engine...
I've neglected my DAZ library for a while, and playing games took over as my hobby. Every once in a while I would update with DIM and start Studio to play around a bit, but I had gotten burnt out converting scenes to work with Blender Cycles render engine. Anyway, this latest update I got the new version of DAZ Studio. I was pleasantly surprised to see a brand new render engine! No more tedious material conversions and time consuming scene editing in Blender! Perhaps now I'll get back into things using Iray. Here's something I put together today just for fun. It took almost 2 hours to render using a GT 630m. Next time I'll see if the CPU does any better than that. I like having the CPU free to do other things, though. Final post work in PaintShop Pro.
Okay, posting images in this new forum isn't working... I attempt to attach a file and get an endless "uploading" message until I cancel.
I complete agree with the camera subject, you can see very good something somewhere with just your own eyes, then you take a shoot with no lighting reinforcements and you can get a crappy photo. I had years ago a discussion with some artist who was stubborn in getting good and realistic images of human bodies just using the backlight coming from the window in Vray.
I told him to put some subtle extra light or at least some concealed white plane to act as reflector and he always refused and never got a truly realistic render till I told him the same that you did. We must understand our rendering software as a camera with its issues and not as a human eye.
After few days I told him so, he saw the outdoor filming of a movie, and noticed how the illuminators deployed white sheets and concealed mirrors to reflect sun lightning and reinforce the lightning effect. He started to do the same with Vray and his renders started to improve dramatically.
AKA 'where will YOU be when your acid kicks in?'
You can upload your pic to a free hosting like tinypic and paste in the image icon the adress of the raw image. Im interested in what you rendered, I have a GT620 and mostly had a 1.30 min render first time, then i learned to configure and undersample a bit the engine and im getting renders in 10-30 mins.
Let's see if this works... Original was 1920 x 1080, but I downsized for posting.
OH, Ok. If the background its poligonal and not a curved plane then maybe so mucho bjects and polygons retarded a little the rendering, anyway, our graphic cards just helps a bit, a little bit.... For a great performance a Titan series is needed.
Yes, a Titan or 980 would be nice, but I'm stuck on a laptop for now. The laptop also has an i7 @ 2.4 GHz, so that would be up to 8 threads running amidst background processes. I figured that loading both the cpu and gpu might only provide marginal improvement if the engine has to divide up the tasks between different code types - CUDA vs Intel instruction sets.
The scene I posted has four spots in addition to an HDR image. I ran lots of low resolution tests to get the lighting where I wanted it. It took longer to set up the lighting than any other element of the scene, but that's how important it is to composition.
I keep seeing a guy like this in Facebook, so decided to render him.
I wanted to make the beard curly, but hey, what can you do.
It's about Al'Quaead's facebook???
Anyway the skin looks nice. 
The skin is Nevio, which I think I got with Michael 6 pro bundle or something (can't find it right now, hrm). Has a good olive undertone that's a nice launching point for medium tone skins.
I then modified it a bunch. (Darkened, fiddled with glossy/top coat)
I'm starting to think I've been making some mistakes with glossy and top coat -- I often erase the Specular map that gets converted over, but now I'm thinking I should, instead, turn limits off and adjust weight to 1+ as needed.
I've also been using Glossy color to add highlights and tone to the skin which is, strictly speaking, unrealistic. Then again, I've liked the results, so.
Those specular maps, at least the ones done properly, provide variance that adds to the realism. Check out the technical aricle I posted a few days ago:
http://www.daz3d.com/forums/discussion/61131/tech-article-on-pbr-skin-rendering-warning-lots-of-math
It has some useful suggestions for improving the quality of the skin. It's an nVidia article, but not specifically on Iray or D|S.
Yah, it comes with M6 pro bundle, but I find it easy and usefull for clothed renders, but for nude or partially nude has lots of tone variances, like someone tanned just form above and the inner part of the armas and waist are whitier
Most of G3 bumps and specs which comes as factory defailts are flat and crappy. I had to pre-work all of that increasing contrast and adding some noise and details.
