Haha, patience isn't something I have a lot of either, so I know exactly what you mean. On the contrary, though, I think that lack of patience did you a favour! The absence of intense shading in the hair allows room to see your (in my opinion, wonderfully stylised) linework, and can also be easily taken for light shine, which helps to set the whole picture off just that little bit more.
You're welcome! I look forward to seeing more of your work in the future. !
