after looking back and fourth from my hand to your hand model, there's one strange thing I noticed, your hand looks like it has a flat palm, while mine looks concave (like it's holding a semi-flat ball). most noticeably is the muscle connecting to the thumb. it seems wide, but not thick. one other think I just noticed about the thumb (maybe its just the perspective) but it looks a little too rotated counter-clockwise, no matter how hard i try, I can't seem to get my thumb to be in that position.
:huf: alright, now that i'm done pointing out what I notice that could be better, here's some things I like about it. I like the back of the hand, the tendons seem to be just far enough out, but not too far. the wrist looks pretty nice to me, it has good creases, and tendon placements.
so, that's just my "two cents"
I hope you know what I'm talking about
