Sketch:

I didn't really get a whole lot of response to Blossom, but I still wanted to go back and draw Sunshine's super form since she has officially become one of my overall favorite Cures and it seemed somewhat appropriate for the summer. (not to mention... in terms of details it seemed a bit easier than drawing Cure Rhythm as a follow-up to Melody... I'm saving her for another week...)
As for the sketch, the only real change was that the bottom of the boots were traced in because I wasn't happy with how my attempt came out. Beyond that, most of the other details were cleaned up using my previous drawing of Cure Sunshine to keep things consistent. Happily, most things still lined up pretty well so any changes aren't major.
Pretty Cure and all relate characters, including Cure Sunshine/Itsuki Myoudouin, belong to Toei and any/all other respective owners. I don't own the character(s) in any way, shape or form, I'm just a fan!
