Actually, I never made a 12 barrel version. I judged it fairly as I tend to do. You judge quality verses size. Is this quality enough for my map, is it a regular kind of quality, does it stand out or does it fit with the regular models?
My style is quite different from yours. I studied the model and thought about picking parts, but I just couldn't figure out a a nice pick that would blend well. I might yoink some part later though, possibly. Then again, I might yoink some of the arm structure. Also, was thinking about adding the head, but idonno, somehow it felt.. too.. sci-fi. So I figured I add a goblin and some form of seat.
Actually, my models I is a lot easier than an instantaneous 8 barrel shooting.
First off, it looks awkward when 8 barrels shoot at once. Second, all I have to do is make the gun spin and the ammo at the back to decrease.. and just add some glow effect. The rest is done with particle effects and sound effects. ;D
