Don't be TOO hard on yourself :) I imagine this one was still fun to draw, even if it gets relegated to the scrap sketch pile.
what did the ink do? I'm perversely curious to try something like that myself.
Well, I put the ink on top of the pastel and it immediately flattened the image. I went back over the ink with more pastel and it was somewhat receptive, but the black sucks the life out of any of the colors you put down. If I were to try it again, I'd consider a different color ink... not such a heavily contrasting color.
