Mmm, I dunno. This has too much of a "Eater of worlds/Destroyer" feel to it due to the boss's appearence. That alone makes it feel rather uninspired, though you may not have known/intended to make a terraria refference. You might want to do a bit more to make it less generic.
Well The Boss Is Basicly Shooting and attacking the Center of the mouth so i dont see how pewpewing his mouth and body Has anything to do with Eater of worlds
