Black Locust Tree with Pitt Big Brush Pens

Pitt Big Brush Pens

Stillman & Birn Epsilon 5.5x8.5" hardbound sketchbook

Blue background prepared in advance with diluted acrylics

This was sketched at my friend Melissa's house. She has a back yard filled with bird feeders and beautiful trees to sketch from the windows. This Black Locust tree had interesting shapes and bark. I used my Pitt Big Brush Pens over a toned surface. I really liked the warm colors on the blue paper. I thought it would blend with the pens and make the warm grays more neutral, but actually it made them seem even warmer by comparison with the cool color of the background.
