I decided to go in a bit of a steampunk direction with this monotangle. I like copper and green together and I‘ve been wanting to do more Zen Gems, so this tile made my artistic soul very happy.
Zentangle drawn on Strathmore Vellum Bristol using a black, Micron pen. Coloring done with mixed brand colored pencils, Crayon and Distress markers. Shading done with graphite pencil.
