She's got a threatening kinda look.. nice so far

What a nice, ambitious angle to be drawing from. :) But despite the mystery of perspective, you should narrow in the bridge of her nose. Even though the joining of her forehead and nose is much closer to the viewer than the tip/bottom of her nose is, the join of the nose is still thinner than the bottom. As it is, it looks a little bit as if she has a snout rather than a nose. ~__~ Anyway, if you cinched in her nose a bit, I think this piece could benefit a lot.
