Cute. I was gonna say the ears and the noisy gem were kinda giving me an off-vibe but you've addressed them both. Since that gem is such a saturated hot pink, you should have some of that color bounce off a tiny, tiny bit. Like under the chin, around the nearby fur/collar, etc...subtlety is key.

The colors looks a little too desaturated for WoW (only a little bit).
Maybe a bearclaw can help here.
