Here’s the second drawing I did at Swansea’s graffiti tunnel a couple of days ago. I like it a bit better than the first one I did. I think the composition works but I still don’t like the effect of the charcoal and chalks on the brown paper. I should have used black paper, so it’s a return visit for me …… when it stops pouring with rain.

Maybe your own concept called for smooth paper instead. It really works for this viewer very well!
Thank you 😀
