kinda looks like a double barrelled super soaker. i think u should go on google and search some images and see what the actual weapon looks like and model based on that.
I fucking admire that, apoc, give him time, evryone who started out sucked. Ok, try not to use cubes, like the other kid said, and try cutting parts out and things, the make a cleaner look, and if u do use cubes, line em up, try not to show seams, ill say gj for ur first try, jkeep it up!
