Thanks for the comments. Indeed the palm of the hand is quite a challenge. I tried putting some lines and create more padding but it doesnt come accross that way on the pictures, perhaps chaging the lighting might help. I'll have to play some more with it. Also the joint area between the wrist and the hand/palm is a bit of a pain. I have a line in there that separates the two areas perhaps too much, the transition between them is not very smooth. Maybe I should have just added those details in the bump map.
Anyways, I think I am going to start working on the skin coloring and such pretty soon before I burn out on the modeling.
