Okay first of all...The sounds. Some of the choices of the music here is horrible. Especially with the "Let's Fight" scene. Also with the talking Alien black robe figure. The sounds are just amplified to egregious levels it hurts my ears. But anyways back to the animation at hand. Well you did a good job on the animation, but the story is literally confusing. All I could understand from this is well from your Author's comments. The animation itself didn't explain it further yet give a solid point. All I see here is people go to some kind of cult church, then get into an abrupt fight for no reason, then one guy gets punched and it ends there. I...I really don't know what you're going for here. At first I was expecting some gritty, hallucinating, and creepy skit but this just looks incomplete to be honest.
