This is really beautiful, as are the rest of your gallery. Something I really love is the textures you use, the gun has several different patterns and the rest is smooth shading. The wings and hair are done nicely and the light source and wind is clear.
One thing I would have you work on is the fingers and eyes. The finders look like leaves rather than digits, and the eyes kindof have a blank stare, but perhaps its just the pupil being a close color to the bangs. But brilliant job nonetheless! I look forward to seeing more from you Kue!
