Sketching with paint

I love line work, and generally only utilize the pencil and sometimes a pen. Recently, though, I’ve been working with the push and pull of a paintbrush, and I’m very happy with the trembling energy it leaves on the paper. Here’s today’s sketch using watercolor (M. Graham) and a no. 2 Kolinsky sable. I still relied on pencil to start the sketch, then erased draft lines after painting. The sketch was drawn over a block of color I laid down a few weeks ago, when I was testing new paints (M. Graham) and saturation on hot press paper.
