Here are progress shots of 4 angel illustrations for Koine motion graphics. I did these on homemade scratchboard: 4-5 layers of Utrecht Gesso on masonite. Each coat sanded smooth with a palm sander. India ink painted on with wide soft brush. I made this in preparation for the Emmanuel Lux album cover, but I wasn't satisfied with it. After trying it again with sharp tools, it works pretty well. There is some underlying texture from gesso that didn't get sanded down enough.
