Tsukiko animation test

I've been working on this short animation test for a while in my free time. This is my Rise of the Guardians fan-character, Tsukiko, transforming from her human form to her hare form. You can read more about her here: tigrin.deviantart.com/art/Tsuk…
 

I was hoping to make this a looping animation, with the hare transforming back into human, but I have yet to come up with an interesting idea for that...
