Here's a second doodle I did today (you can click on it to see the full-sized version). My pen ran out of ink near the end, so I think this'll be the last sketch in a while and I'll go back to reading during my spare time.
I threw out the previous one (of the dancer) after I took a photo, since I had made it on scrap paper and there were other things on the back side. I think this one I'll keep. I didn't do such a good job on their faces, but I still liked the overall feel of the piece.
