I made some back armor to hold the backpack and cannon out of a large plastic bucket and after a lot of trimming to get it to fit just clamped the polls on drilled and attached.Looks great dude! Good job with the lifts. I'm just wondering how you did the skull pieces on the back. I've been meaning to do something like that, with skulls on poles, like Chopper, but haven't figured out an effective way yet. Huntorial?
