yeah, face needs some work and the genitals are definitely deformed. but kudos to the guy for even attempting to sculpt such a complicated part of the anatomy. most would only sculpt the minimum and make it 'work' with morphs.

agreeing with others, to get a 'realistic' look there would require a really dense mesh to accomodate just a few variations on shape etc.

plus i agree with Laurie, the feet/shin area needs refining as well
