It's been a while, I know.
You should have a page with your watercolor wash or your "hatch" marks on it. On top of this you should have a drawing in pencil.
Here's what I want you do, get one of my uni-ball pens if you don't have one of your own (Art 3's, just follow the lead of the Art 4's), and continue on that drawing by going over what you have in pencil, adding to it, and/or shading.
Just make it look great again ;)
