Pushin' though hard times.

Your faces are great! You really gotta spend some time and figure out the anatomy of the rest of the human figure to a similar level though. With hands especially, the only way to work out the quirks seems to be doing loads and loads of iterations. Try thinking about hands in different ways, and then apply that knowledge to create the illusion that you know how to draw them. Something that worked for me was doing studies of what different kinds of hand sillouettes look like and combining that with a rough idea of how to construct something hand-like.
