Cool!! I really like the overall outfit design here. She looks great! c:
If you don't mind me offering some constructive criticisms; I feel like the leg closest to the camera is a little off. Her leg and stockings indicate that they're facing to the left of the screen, so I think her foot would look better pointed to the left as well--but her boot and foot seem to just suddenly twist forward and face the viewer. Maybe it's the lines in her leggings that are throwing me off. They could possibly just be drawn as if they're twisted slightly.
Amazing detail on the chair, by the way...!! Usually most people don't bother with stuff like that. Kudos!
