Gosh I love bunnies, too! I even have a pet bunny at home huhu.
I have a couple of rabbit characters based off of the Al Mi'raj, if you haven't heard of it already! My own Mi'rajs are just inspired from the legend and have different but similar abilities. I also recommend checking out Bunnior on DeviantART; they had a closed species called Bunniors but I'm not sure if they still make them. Regardless they have some recent adopts, and maybe you can get some inspiration from Bunniors.
Good luck with your bunnies!
