Took care of a few shading odds and ends. Brought another piece of the snake through some clouds in the ditch (tattoo lingo for the elbow "pit"). The clouds covering the snake will lighten quite a bit and create a cool hazy effect when all the scales and color goes in.
Also capped off the shading around the wrist and a bit up the back of the forearm. Probably one or two more outline sessions for the upper arm then shade away until completion...
