Am idea I have had a few times, thouhg it might not fit the new user truth to be told, is to do a Revision sort of ocntest. As, the ones participating redo a render they did a while ago. First they post the older one (not gonna give a time as I think there is people way better than me to decide those things
but it should hopefully not be a render done just a few days ago.. Unless perhaps if the one doing it started at that time etc) .. anyhow, first post the older render, get feedback etc and than work on it. And for the actually contest entry thread post both the older one and the new one, and perhaps tell what the changes are etc.
Though it might not be that good fit for the New User. I just figured I could throw it out here, it's an idea that's been in my mind for al ittle while.. not sure it Can be done in the first place though *smiles*
Edit - and I just Now realised how old this thread was.. *sorry* I just saw the it as it came up, read the posts but didn't read the dates *hangs head*
Second edit - On a second note, about the size. I think I read somewhere that SSS shaders required the render to be 1000 or bigger, or they dstored or osmething like that. If so, perhaps raising the size a little would be worth cosnidering (I am the first to admit I might have missunderstood what I read or it might just have been that specific product. I Think it was in Zev0's Growing up thread)
