The Hair going over the collar bit needs to be overlapping the collar more.
You could overall clean it up, there are places where the color goes outside the lines.
The basic drawing is nice, you did well on the ears, the "lips" could use some work, although I suspect it's meant to be like that because of the candy.

The bits of "highlight" or "light" adds well to the drawing.

Is that okay? I was trying to be honest.
