I understand that it is an outline, but if I were you, I would do what was mentioned in a previous post; get a tile, hold down your mouse, draw your path, and go over it. And for the blackness, the corridors is a very good idea. Make it look like more than just a level, a level is a story and nobody wants to listen to a story that is lacking multiple characters, details, and side stories.
