Very good!
However, I do think that the angle of the(her) left hand doesn't quite match that of her arm - it almost seems like the coat of feathers is something glued to her arm at a weird angle rather than being it.
In addition, I also found her pose slightly out of proportion; her left leg at a strange angle considering the twist of her torso. This might be on purpose though, and it's not to say it's a bad thing! If it is on purpose (and even if not), it certainly gives a slightly more twisted and eerie feeling in the picture, which is in overall captured perfectly through the dark colours, bosom, smirk and brutishness.
Very good, keep going!
