The thumb looks good on his (our left, his right) hand, though the index finger should have the vertical line overlapping the horizontal line (the last finger joint) to give the illusion that it's curled under, rather than having the horizontal line overlap the vertical.
Hands are usually pretty hard but you did really well especially on the other one. Keep up the good work

His feet seem pretty good overall, though the depth perception could be a bit better. It looks as if his left (our right) leg is a bent too much and he's leaning.
