much less noise on the eyes less specular on the hair, good work

are you adding some sort of bump to the blood?  On the shirt it looks really thick, to me it stands out a lot, perhaps reduce that a bit.   Looking great though

On the outermost hair layer I'd thin out some of those "ribbons" a lot.

Eyelashes ccould perhaps be a little thicker? They seem almost non-existent on the right eye.

This looks fantastic .keep it up man . i think all the changes that can be made are told above . one thing i would like to add is , try to make the hairline more natural , i mean near the hairline there could be small hairs and a little bit non symmetry  .  but overall it looks fantastic  . i loved it .
