Thanks! I was thinking of doing that, but I just couldn't get it "right". I'll have to mess around with it later after I finish all the main animations.
Love the design, the hat is especially a nice addition. I do wish that the hat would move or a bit though.
I think the problem with the animation might be due to the fact that the hat isn't sitting on her head quite properly, the place where the hat meets the head/hair doesn't look realistic. (Usually a hat would go around the entire circumference of the head, including the hair, but here we can see a part of the hair that goes 'behind' the hat a bit') It's a bit hard to read.
Not saying you have to change that but you should keep in mind that can make things harder to work with when animating. Anyways I definitely agree that the hat should move back and forth a bit, especially since it's so large, it only makes sense that it would have a more pronounced effect for animation and it's a large static part of your character that needs some movement to match the rest.
I very much like the character. It has some charm.
