Ugly ears
Certainly a decent "opening titles" freeze frame for an animation. I'd certainly recommend that you use it for just this reason (perhaps that's where you got the idea from).
The form of the character is good, although I would suggest that you hide her ear behind her hair, as it looks quite ugly and out of place in such an environment. I'm aware of the exaggerated eye size and this might account for it. If that is the case, while eyes can look captivating and beautiful, I cannot say the same for ears.
The colour choice is quite bland, though that could be something to do with the context, if this is taken from or will be added to an animation. The only bright colour being the blonde of her hair - perhaps something else in her clothing could be bright, to bring the image out of the page, somewhat?
