The bunny is very cute.
The only suggestions I have would be to move the ears a bit farther apart, so they attach a little more on the side of the skull. Not a lot, just 2-3 pixels or so.
I think the foot on our left might doesn't stand out as strongly as it could. The hand, torso, and foot are all about the same value. The torso and foot follow the same shape as well. Maybe shadow the torso a bit more to make the foot pop out more.
Really nice overall.
