The first one lacks depth, and the text needs some work. Those little blue specks at the bottom I think would look better on the outside of both sides of the render, and I think it could be sharpened. The second one. I think it was a good general idea, but I don't really like it too much. The disco balls are placed wrong in my opinion; they are in the focal point of the man. It is kind of bothering me that I have to turn my head sideways to see it straight also. Text needs work.
