75 Day Sketch Challenge - Day 13

After a long day, I still managed to get a sketch done.......just barely considering the time.  Rather than trying to decide on a subject of my own, I chose to grab one of my books by Claudia Nice - Painting with Watercolor, Pen & Ink.   I'm hoping by occasionally practicing examples from one I value highly as an artist teaching pen and ink, I may understand better the use of line for shading with my own ideas.
