I like the Ren & Stimpy vibe I get here. It has a lot of nice detail to it, especially the ears, and the wrinkles and little hairs on the face. I just wish there was more to it than just the bunny's head.
Also, you said this was a piece made for Easter, but there's nothing Easter about it. If you drew an entire body for the bunny and maybe added an Easter basket in his hand or something it would make this drawing so much better.
