I absolutely love this dress. My only complaint is the corset top, crown, and arm bands seem almost drab compared to the skirt. I understand the skirt is the main focus but I think some sort of glitz up top would just add to the magic. That being said, the crown seems very "heavy". Something a bit more light, maybe playing off the wings would look wonderful.
The wings could use a little bit of a design too. Not too much because i feel it would overthrow the entire aspect. Part of it might be the angle though, not sure without a close up.
Excellent work though. The concept and impact are AMAZING!
