Its lacking focal and the bg is a bit to plain. Looks like you just to the smudge tool and smudged green and black everywhere. Also, I dont understand that grey colored smudge to the left of the render, takes away from the render a lot. The BG is a bit to over contrasted and lacks color, mainly to much black. The text is nice though. It needs work, take a look at the tutorials section, its been helping me progress very fast in my skills. Even if you dont follow a whole tutorial step by step from start to finish, you can still pick up little tips and tricks and just throw a whole bunch toghether to make a master peice. Dont let my CnC discourage you, turn it into motivation. Keep at it man
agreed with ALL of that, but just to add try to work on your coloring a little bit. whats amazing though is that most people SUCK at text, and yours is pretty good like atreyu said dont let the criticism break you down, use it to get better
