@Valerie-Light Your character has a lot of fun interests! I especially love the go-kart. The ink wash is fun too. Some of the expression pictures do not look consistent and like the same person. Close, but not quite. You could do the line thing on character sheets (not sure if there is a name for it) where you draw straight lines across a page. Then draw the head several times, but with different expressions. The lines could be for her eyes, mouth, nose etc. So the line up. That might help. I hope that makes sense.
I have a hard time keeping my characters consistent, but have noticed that when I draw the lines, it does help some.
