Oh, I can see how there's a mistake in her gender. I totally missed drawing the chest. o.o

Also, I noticed that the eyes seem to have a bit of a male quality. The lines are too... "strong" so to speak. I could have put a bit more feminine quality in them. I think the fault could be in the way they were tappered.

And as for the ears, the idea was to make it look like they were pulled back a bit. Kind of like a dog would do.
