Looking good! I'm going to say pretty much the same things. Mess with the color balance a little, make the credits not quite so in-your-face, and try to make the forelock and tail look a little more natural. Especially the forelock. The hairs look like they are too thick and come to an abrupt stop, versus fading out more. :D

The shadow could be a bit more pronounced and, based on the lighting, should be more to the right and elongated.
