I love it! Warcraft just doesn't have enough female characters. And concerning the breasts, leave 'em as-is. I find that she's more like a village "teenager" than a grown woman, so if she's a little flat chested that would make sense.
One thing you do need to add though, is a portrait, or at least a camera. I wanted to use it in a map I'm working on, but without a portrait or cam, it just doesn't look right.
