It would be interesting if you picked a position for it, a still from this animation, i mean, and then added some idle motion. Eye blinking, smiling, ear wiggling (lol). Just little things. Animation in an avatar has to be approached subtly, especially at this size. Smaller gifs or sprites can pull it off, but this just seems distracting.
Adam: i have to disagree about the eyes, i've noticed this forum becoming (well, maybe it always has been) more focused on the 'average' outlook on anatomy. Not everyone is seven heads in height, not everyone's ears are level, not everyones lips are a certain width, not everyone's forehead is a certain size. Sure, there is a point where these issues border overexageration, but the eyes... they are perfectly fine, they fit the piece well, in fact. I'm surprised you picked out the eyes and said nothing about the teeth being RIDICULOUSLY large. This isn't directed to you personally, but i think that you should at least understand that the artist may be making the choices out of preference and not ignorance.
