Critique my drawing skills, Southperry

Face is crooked, the mouth is to the left. Also, her face is too tall, it's probably the nose being too long. Or consider lowering her eyes.

The nose looks odd, the nostrils and tip are the same size. Her chin looks too asymmetrical. Make the eyebrows a bit more wider.

Good job on the hair.

Ah, dang. I was making the face crooked/mouth to left to kind of match the pose she was doing, but now that I see it, it is really bad. That's upsetting.
I will work on fixing the nose and eyebrows. How should I change the chin to be better?
You think there's any way to change the crookedness/mouth to make it look normal without redoing the whole piece? If not, I'll probably just have to hand it to her as is. She probably won't notice, but I will be sure to try and do that better.
