I have taken in a ton of youtube videos reminding me of how important it is to push your creative margins. I am very excited about this one. It was inked using a red sable #3 paint brush in Bombay Violet india ink, alcohol marker, and old faithful---> (Paper Mate Flair M). Purchased online through Dick Blick art supply. I am very happy with the results. I love the variety of line weights and depth of color.
