Cleomedes Enters Shadow

Sketching: For this sketch I used: black Strathmore 400 Artagain paper, white and black Conte’ pastel pencils. In addition a small artist’s brush and powdered Conte’ white crayon was used for blending. Contrast was slightly increased (+2) using a scanner to better match the original.
