In the video I used a sheet of Strathmore Grey toned paper and some liquitex basic paints such as the neutral grey 5 and a white.
The paper really gave a great mid tone to help balance out further shades of grey and together with the inks of the undead corpse, it really stood out as a cool concept kind of sketch.
