Face Transfer and Illustrated faces

Can anyone explain to me why when using the Face Transfer plug-in that some illustrated faces (comic book characters, etc) work and some don't? The face is the right kind of image (humanoid) and similar to a photo but some work and some don't. I thought it might be because the ones that worked were in color and the ones that didn't were black and white, but that theory doesn't seem to hold water either. I took an illustrated black & white image of a human male and colored it and the plug-in refuses to run, meaning I get the error message to try a different image. Yet I can take an image of a human male from a comic book and it runs fine. Am I missing a requirement here? Do I need to show examples?

I imagine it can only work with what it detects as a face since it doesn't use marking
I use Facegen for example which has markers you place for features and that handles illustrations fine
likewise Crazytalk 8 which I use for iClone Character creator, the extra help enables the programs to define the face
Almost surely because of how mach shading the pictures have but to sould a couple of successes and failures would help if you think that's not the reason.
Well here are 2 images. One succeeded (Seann William Scott), the other failed.
Probably the mustache. In a picture (photo) you might get away with it, but in an illustration it's hard to say for the recognition software to tell a mouth apart from a mustache. It's very likely it's calibrated for photographs, less for illustrations. To solve it you might need to do testing to see what face transfer can read (and what not)
For instance you could photoshop the mustache away and try again, and add the mustache later.
I hadn't thought of that. Now that I think about it, the other images that worked, didn't have mustaches. Worth trying anyway.
Just a guess but the successful one a a smooth realistic gradient showing (much reduced) details and the second has even less than that but maybe more importantly it has false gradients that are unnatural, flat, and don't accuratey reflect anything like you'd see in the natural world. See has the black inking outlines bleed as a gradient on the 2nd?
Also, maybe just as importantly, the 1st image looks as if created from a real photograph by a computer algorithm so even with reduced details is is likely to be very accurate while the 2nd picture was clearly drawn by hand and not nearly so accurate either.
Thanks for the analysis, but I tried removing the mustache and tweaked the skin painting in a similar style to the first image and believe it or not it worked. I'll have to post results later. So apparently not being to determine the space between the nose and upper lip was an issue. I'll have to put this thru further testing to see if other images I had issues can be transferred successfully.
They's good. A surprise too as the 1st image has both a mustache & beard.
