I have a silver lab who I periodically find in quirky poses that warrant an artistic rendition. This was a fun instance where she was watching television in my basement. I used a larger brush pen with a pretty broad range of stroke widths. It is a bit more challenging, but lays down a very well shaped, and saturated line. I bought it to do large fill work, but has become a favorite for full detailed drawings.
Ink used: Pentel Standard Brush Pen – Medium Tip
