Some sketches and some randomness. Seriously, I draw and draw, allot. Its a awesome habit that I think about as philosophy and I treat it like a muscle. I try to get in some freestyle drawing in morning while drinking some coffee. Then get in some "thoughtful" drawing. Then the rest of the day its working on illustration, comics or painting. I always try to get in another hour of doodling before I crash. Sometimes I draw while watching the latest episode of Law and Order, and just try to sketch scenes and compositions, pause button, sketch, another criminal on the loose, pause repeat.
