Ballerina 25 minutes

This began as a 15 minute pose, with scribbly pencil construction drawing, but I liked it so I stopped the clock, erased the pencil until I could barely see it, and then redrew it with a ballpoint pen. I messed up her nose, so I added a mask that isn't in the original photo, to cover my mistake. Then I erased my pencil marks completely. It's about 4 inches by 7 inches.
