It looks like she's either been crying or wounded. Neither prospect pleases me much at all. I hope that whoever she's aiming at will get their flank whooped good.
The straight feathers almost look like crystals. If you were going for the impression, it worked, if not, well, you produced it! I like her hair here, the uneven and frazzled appearance suits this perfectly as well as looks great on Twily. And the thin legs and a lighter frame somehow underline both her femininity and fragility and the sheer power she has amassed. Well done!
