The cartoony bunny

For digital painting class, we had to have three character designs of our own so we could then do three colour keys (variations) of the package. It feels like it's been ages since I tried designing characters, but I do want to use these guys in something, maybe our next animation assignment:

I got extremely helpful critiques from our teacher today but haven't fixed the designs yet, so consider them a work in progress.
The same goes for these three colour keys!
