This is a doodle based on something I drew right before going to sleep last night. Many of my ideas come at that point of the evening. I'm at the most exhausted, about to surrender to Morpheus and then it hits me—a new idea, a new illustration, project—you name it.
If my foggy brain thinks that an idea is worthy enough to stretch out my arm from under the covers, it gets recorded in my sketchbook. Otherwise, it's completely lost. The problem with sketching that late is that sometimes I end up staying up another hour or two. I'm glad I did in this case because I got a lot out of my head. I must remember to put pencil to paper more often.
How about you? When do new ideas hit you?
