It's been a good long while since I've seen a work like this, but I can't decide what elements are flaws, or on purpose... so that in and of itself is a good thing. Keeps us asking questions about the lady formed by her fears and worries. The implied text at the bottom suggests this is more or less a fully fleshed out piece, though it does look a bit undefined: in her kicked up lower leg (cut off at the knee), and her outstretched hand, which looks unformed or bird-like... the latter could use some definition.
Try doing one of these every few months or so, I'd be curious to see how they evolve!
