I recently read a genderswapped version of Sleeping Beauty, so this is really a great visual for that. She looks more adventurous, which I think suits her personality from the film. There is still an element of grace in her positioning, which is really emphasized with the way the cape flows behind her and the way her right hand is poised. It's a lovely image.
This is my favorite of all your costume swaps. Aurora was my favorite Disney character for a long time when I was a kid, so it's great to see her drawn like this. You stayed very true to the original movie's art style, too (actually, you did that on pretty much all of them). Awesome work.
