Well ye definatly v1 as everyone said before me .. but i think the c4d on the right is a bit too sharp .. you should make the render more sharp and blur the c4d more .. you could download some nice splatter burshes from deviantart .. then ctrl + a edit > Copy Merged then ctr + V .. then duplicate the render .. erase some parts of it with the splatter brush .. then move it to another location .. allso try flipping it around .. vertical / horisontal / 90 etc etc. see if it will look any good
