I Screwed Up

that render is just simply weird
Personally I think v2 works best, simply blurring a BG like that usually doesn't work for depth
Nice concept Maybe you just overdid it a tad with all those colors near the render :S

 

like v2 but maybe just hide some of the white line at the bottom

 

yah I can't say I like it, needs depth and the long line tail you got on v2 isn't looking good but v2 is the best one.. odd sig though you got my interest
