Isn't she lovely? I don't usually find androgynous people attractive but she is my absolute exception.

See, I actually read your character as older (I think because of the hair). Some of what is adding gender, as I said, is the clothing. Maybe try the same thing in pants instead of a skirt and see which way it's skewed after that? Something else I thought of that might help you is video game character creation. I only mention it because I've been obsessively playing the Sims3 but getting "off gender" characters is relatively easy.
