Face is nice, i like colors and shadows too but there are a few points that in my opinion you need to fix:

- Body proportions are a bit messy, chest is too wide in comparison with arms and hips
- The bra seems too on the left, should be placed better.
- Wings, i didn't notice them when i firstly look at the image, i think they seem too dark and they merge with the background, you should add some highlights.
- Fingers on her left hand seem shorter than the ones on the other hand.
- Last thing, the piece of armor on her shoulder is the most noticeable thing because his definition is better than other important parts. At least this is my impression while looking at the drawing.
