I think that is a pretty nice avatar. It's full of emotion and has a soothing aura, for some reason. A fine choice for an avatar, in my opinion.
Oh, by the way, I did not specify any rating system, because I always felt like the x up to y rating system is distracting us from making a proper judgement. I feel like we should be pointing out what we like and/or maybe what we do not like about the above user's avatar, instead of just rating it on a scale.
