the texture maps where made without picking up a brush. sort of a pre-textureing stage.
Nice ear - I was wondering what you meant by doing the textures without a brush? Are you baking FG or AO shading into textures?
I notice 2x ‘5 siders’ in the lower cheek area, how do you get on with these when it comes down to any form of facial expressions, do you get probs at all?
No, not at all, see this test of a smiling expression, which is one of the strongest deformations to the geometry.
Also on your render, what shader are you using or is it just a standard blinn with the good maps on? Its a great render, it has a very subtle haze to it like one of those summer evenings
Thanks, it’s all the same misss_fast_skin shader, no layered fancy stuff, rendered with an hdri and with reflections switched on.
LikuidSnake, the front looks ok so far, but the back has a bump because of the relative differences in denseness there… but I guess you’re working on that.
shadowman99, I agree with JayEdwards except the bumps are probably not too high, you just need a bit of sss in there, for instance the misss_fast_skin. Otherwise, no suggestions because it’s very good! 
Daniel, you seem to have a damn good handle on the anatomy and on what you want to adress in the future, personally I don’t see some of those problems you mention as big problems, due to how different individuals can look… just keep checking real reference, don’t worry too much about muscle charts the most important thing is the real living person. 3d.sk is the best for this I’ve found. But your model already is so good it’s getting hard to see what more to tweak.
