Character Development - Rabbit

The rabbit was one of my favourite silhouettes. The top ones feel very much like they would suit a children's story or cartoon.
I like the bottom one for the way the ears are a part of the character. I think how oversized they are would really make its shape quite distinct and recognisable silhouetted.  It would be excellent to do but my lack of experience with rigging in Maya will probably make it difficult as it is radically different from a basic human face. It would be a lot of work to rig up the ears as part of it.
