So hello /CGL/, I've been planning to make a Techpriest cosplay for a convention in February. While I've pretty much figured out on how to make the Axe, and got a friend to help me out with robe sewing, I cannot seem to understand how to make the backpack.I've collected various reference images, but it just isn't clicking. I even tried tracking down any free Spacemarine backpack which is human sized scale (I'm 5'9") and use it as a base, but I haven't really tracked down a proper one.Anyone out here, if you can please maybe give some suggestions on how to make it, it will really help me out. My plan is to put a mechandrite arm at one side of the backpack and a servo skull at the other side, acting as a light.
