Drawing II at ISU

Self Portrait Value Study.
Is approximately 24x32" And took approximately 26 hours to complete.
I had a picture taken against a black background, which was then pixelated to provide something of a map for the grayscale values that were to be placed on the page. The process consisted of laying down a combination of Vine and Compressed charchol in layers and then pulling it back out with an eraser and blending stump. The effect is that of a very soft velvet texture.
