I think this drawing has potential, but I'm being distracted by how rough the lines are. That may have been intentional, to show that her hair is messy and she's concerned, but whenever I see pixelization of lines and sharp edges on them where individual pixels can be seen on an image this large it makes me think that maybe you weren't really in control of them. I normally use a low opacity/flow when making lines so I can better control them and I just go over them a few times until they're as dark as I want.
