Sigh + Eyeroll = ...and heeeeere we goo... Captured the moment very nicely. I particularly liked the manner in which the expression changed, and the hair motion toward the second half of the animation? That was very well done. Also liked the tail turn, though I did find that its lack of motion in the earlier part of the anim made it feel a little bit flat. The movement was very nice when it happened though.
Now, having said that, I personally assure you that I can't do anything like this yet. Therefore, I'm not exactly an expert, but am merely stating an opinion. ^_^
