Hi guys! KM here needing some help on a MoC I've been modifying since 2009. In the latest update, however, I wansn't really pleased with how the arms came out. I'd like to have some help on it, and if you can come up with a better one, that'd be awesome. I'm looking for great ideas on how to make his arm more muscle-filled and stuff.
