Nice. That top one where you've cut it into rectangles and cut parts out looks pretty cool

 

How you made this images???
Did you use a progamm??

Nice, I like the BG, but you should have used more of the renders colors in it. Try duplicating the render a bunch of times, filling up the canvas, merge them together and set it to overlay or soft light. You might want to lower the opacity/fill of it as well. . .
