I've been working on this the last few days. It was an exploration into a new support (Canson Pastel Paper). I liked using the colored paper - I think it really adds something. I also liked having texture to the paper, but I need a bit more practice to get it right.
I think with a few more tweaks I could get this one where I want it, so I might make those and give it another go on a fresh sheet of paper. Although this paper does withstand some erasing, there are spots here that can't take any more adjustment.
