Hey, Kurt.

Awesome model you´ve got going on.
Since you´re still getting everything right before going at the claws, I´d say you have to check the length of the tail, also I remember reading about them some years ago, and their tails were quite stiff, not as prehensile as an ape´s one would be.

I´ve got to say it, the zone around the eye, es top-notch modelling, really incredible, wonder if you´re working on polys or still on NURBS.

Regards man,
