Style is nice, but shapes are just enhanced beyond the point of goodness with topaz. Work on getting the lighting evenly around the render and taking out a lot of the negative space that your background has. The corners have too much vignetting going on, and the random light source (probably a soft brush on screen) on the top right bothers me to no end. Other than that, I love how you blended the cubes with the overlays under his chest/etc.
Work this style, don't be a bitch and quit.
