In revisiting the original 13 Joes, I decided to take Rock n' Roll in a slightly different direction, giving him a desert camo look (like his v2 figure) and an overall appearance that was a little closer to his current Devil's Due incarnation.
The head was the most work, but I finished that first and, since previewing it in the critiques section of this board, have tweaked the accompanying body parts countless times.
In the end, I decided Rock and Roll and Roadblock should have similar looks given their similar specialties.
