You're not wrong, and all he did was butcher a beautiful piece of official concept art from Soul Calibur V [link] and considered it "Abstract" art for some reason. I don't even understand how this ended up being considered as quality/premium fan art.
So why u basically upload a picture, what you don't own, into digital paintings? Move it into photomanipulations, because its only thing you actually did. Right now you just stole the art made by someone and didn't notice him as the main author.
