Were... you the person who posted in orange text? And made autumn and winter avatars?
My monitor agrees most with Alex's edit. But I'm using a laptop so that really doesn't mean much anything. I like the colors, either way, though, and the colored outline helps give it depth. Style crit: I think it looks overly cute, though, like the head belongs on a young child. By the time she's old enough to be a nurse, she should have a chin of some sort.
