Good start. I like that you're using a corset for the top. Are you going to make the gold details at the top of the corset?
@aradia - That looks like a good way to start the headpiece. I hope you'll someday work on it again and post more pics. Maybe it will at least help Darkbeauty with hers.
A cosplay friend of mine did a really nice She Ra costume. If you want, I'll send you links to hers. Maybe it will give you some ideas.
