An even better idea would be to go over it in ink and scan it properly, but you get the idea! Even if you're just uploading a given piece for practice and critique, a little attention to scanning can go a long way.
As for what TopHatKat said, yeah, shading is good. I think you're progressing alright with the way you're going for now, but you know, it never hurts to start shading! I don't agree with his admonishment against bold lines, but his ball is quite good, and if you feel ready to dive into the realm of shadows and highlights, then go for it! Foldy cloth, like your cloaks (which are looking very good), tend to be very shady, so maybe that would be a good place to start? Drawing more cloaks and working on adding more subtle gradients to the folds?
