Yeah it seems quite bland, to be honest. You could add a slightly textured paper background, and make the spray cans more visible, since they are technically more important than the BG itself, and the depth itself isn't too great. Try to make it look like it was spray painted on a wall or something, and give it more thought and throw some ideas into it It has potential, but right now. it looks too bland Add some flavor, man, I know you've got it in you
