Aphrodite's Priestess Picture

This isn't so much to show my artwork than it is to ask for some help.

Her head is supposed to be tilted up. It looks tilted up to me, but I can't help but get that itching feeling that something is very wrong with one of her features. I can't figure out which one though!

Agh! Any help would be great (as always).

Made with MS Paint. Thought about touching it up in GIMP or something, but it doesn't feel that professional.
