Not as welcoming a surface to work on, glass, but when given the opportunity I try to learn more about sketching etc on an iPad. Here was yesterday’s quick “pencil” sketch. I think it was with the 6B setting. Brush, pencil? It’s all software.
Maybe it’s just been a sort of black and white week.
Mountains. Snowplow mountains. The latter more frequently monumentally challenging. Love your sketch, regardless!
