I don't know what others may think, but I think this is one of my best pastels, and there are almost 150 of them online.
It's only a monochrome sketch, but here I achieved what I was trying for, a convincing rendering of rocky textures. There is a center of interest, one stone that is a bit brighter and more detailed than the others.
I've just repaired the image, using GIMP to compensate for loss of contrast in scanning.
I claim to be a professional artist, because I have actually sold a few paintings, though none recently.
Favourite genre of music: anything but rock or grand opera. By "rock" I mean any of various contemporary genres, including rap, heavy metal, techno etc, characterized by raucous monotony. I don't include jazz.
