thanks, yeah I've been looking at those shoulders and thinking they looked off, I think the problem is the gap down the middle and the fact they point up rather than out. Weapons, particularly guns aren't my strong suit, I need much more practice.

Impressive! I like how you did the joints, I had no idea pneumatic T pieces were used that way. The gun could probably use some work, as it seems a bit simple, and the shoulders seem a little detached from the body, but otherwise great work!
