A co-worker asked about my process. I think he assumed that I was able to complete these "Sleeper Series" sketches in one sitting. That is not, however, the case (although I wish it was!). There are a lot of factors that play into me NOT being able to do so but, regardless, I generally have just enough time to lay down the sketch and most of the base colors. It's not until later on (usually the same day) that I go back and add some of the light, texture and other color details to complete the drawing.
Got it? Great! Now go to sleep.
