It's nothing special bro...........I have just applied the Toy plastic material and project the iris and finally give some fake shadow by polypaint.....!!!
The 'minimum' specs are something like an 8800, IIRC. If the realistic specs are higher than a 460, I'm worried about how their engine/renderer is implemented.
dig the pubic hair .. nice job not sure what is happening with the eyes though, are you going for the reptilian "secondary" eyelid ? or a cat-like iris ?
