Sketch:

Rounding out my three favorite Pretty Cures from Yes! Pretty Cure 5 is Cure Rouge.
As for the sketch, the leggings/boots were traced in because of cropping, but beyond that just the usual polishing.
Pretty Cure and all relate characters, including Cure Rouge/Rin Natsuki, 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!
