its funny how people say "the gun would totally win" or somethin like that, i like to say the bullet would win cause the gun itself can only be used to hit people (unless you're mcguiver and reconstruct the gun or somethin X)
Ah, but the gun is understood as an entire means of attack, which includes ammunition and a working firing mechanism.
If we were to follow your reasoning, then one could say that the bullet itself can only move from place to place, and that the force of impact is what would actually win, and it would continue on like that.
You have a great knack for backgrounds! Great use of perspective and I love that it's so dynamic! I like how, despite size differences and that her opponent is some crazed demon thing, the lady still looks so brave and determined!
