THat black line on the right is HORRIBLE. And this just looks like a rip off of burn's style. Sorry 2/5
You dont "rip off" someones style because no one really owns a style, he's trying to learn from wat other people do. However, i agree the black line looks pretty bad but also its far too simple, it looks like a stock/render with some splatter brushes on it. Also id erase any splatter which goes over his face. Get some C4D's in there etc

and have an actual background. good luck

Your improving..
