Bionic Wallpaper

[Rainbow Crash]

So here is this wallpaper I have. It's not quite up to par with what it should be yet so any tips would be greatly appreciated as I plan to modify it later.

[Kaleohano]

heres my unprofessional opinion
the main focus of the WP (the front, as i would call it), is a whole bunch of FUAH! and AH! and awesome bossness n' such! its crazy looking and totally awesome. And the background is a glowing circle. I'd say add some texture to the BG. Give it some FUAH! Not sure how to describe it so i found a picture

 

i wouldn't do it quite as strong as it is in that pic. But a little texture would do it some good i think.
and when all else fails, can't go wrong by throwing some boobs on somewhere (sorry, i had to)

still an absolutely awesome WP though
