Hope it's okay to upload such a small animation! I don't animate often so when I animate I tend to animate small, self-indulgent scenes.
I wanted to animate a magical girl transformation and the closest thing I had is Croma, an original character that uses the power of colors to transform into a three faced bird.
Obvious Madoka references are ok if it's self-indulgent
