You've very well captured her spirit from the show, and the general playful attitude of the girls when they are effortlessly decimating the bad guys like they are just some kind of toy.
Highly anticipating this release!
Comments (I'll update if I see anything else):
-Ice breath effect looks really good, but to me it looks like it's not coming directly out of her mouth. I think you should trim it in like 2px from where it starts. The fade-out at the end doesn't look bad, but I think if you made it disappear from back to front, and maybe even disperse a little like a cloud, it would look even better. *Edit* Or make the secondary effect loop more until the end. I noticed at one point you hit Blossom quickly, and it looked much better because of this.
-Lazer eyes: The hitsparks seem to trail too far away.
Fire sneeze: The flying version seems to me more like a fire fart, due to her attack pose
Spoiler, click to toggle visibiltyIt's cute that she loses so much control on the air version, but I imagine it would look better and more powerful if she was leaned forward with her legs angled back (similar to her Stand version).
