Was she featured in one of your cartoons? It looks like it's someone you know in real life. There's nothing too special about this. There's still nothing wrong with it. She has a pretty good facial expression. It isn't that naughty.
You seem to have pretty good strokes. It looks different than a lot of your other stuff. I think you got the proportions down pretty realistically. Those are some high boots. It's not quite that stylized.
