The concept is excellent.
It is a great idea. Like you said, youir drawing is not that good but i'll just give you a tip anyway, when the brother turns his head, it looks really fucked. You need to give it some depth, other than that it was alright. Also, when he shoots the cops, there heads shouldnot just randomly explode. We should get a shot of an eye shooting off or the head on the ground. And the blood on the walls looks too neat. It looks as if someone painted it carfully. It should be splashed and blotchy. One thing I don't understand, is how the two cos with guns don't hit the guy when they are standing right behind him. Other than that, the storyline is great and i can see a interesting series coming out of this. Keep up the good work!
