I'm getting pretty talented at Guitar Hero 2, and that's about the extent of things right now.
About those Carb-Othello pencils: I think they are a little tricky, since they are so hard to erase if you have even a moderately heavy hand. If you're using a soft paper, there's the danger of abrasion and ruining the surface. I'm trying to remember who it was on this Forum who said that half the battle of creating a good drawing is finding the right marriage between paper and drawing media.
Have you tried 'wiping down' your drawing every few minutes with a big brush or soft cloth and then picking out with an eraser? This lets you work big soft shapes - it's a form of bringing things in and out of the fog. David Kassan showed me how he did this with his drawings. It adds a level of mystery and atmosphere that is otherwise hard to achieve in line drawings. Having an arsenal of good erasers (not just a kneaded one) is key when working this way.
Anyway - I am really enjoying all your drawings here, Michael.
