This was a very quick sketch in red pen. I added colors later from memory. We were having coffee at one of our favorite restaurants, near our home in Rogers Park. Kim and I were talking about one of her upcoming pieces that morning, and this is the face she makes when she is really thinking. I can't imagine what face I was making.
Note: This was an authentic and accidental coffee drop. There were a lot more drops, but I kept this one in.
