Here's a page before I scan it in. I try to keep everything loose. Almost like an under painting. Then I can shape it and paint some more layers over it in photoshop. The main focus is on value. Something I need to work on. Always reminding myself to not jump ahead and just get the lights and shadows to a place where I like them. Then I add in details. Subtle stuff goes a long way. That's another hard lesson for me.
