As Rayna said, the distorted aura clashes with the background color, Personally, I think the stock is blended in bad, I am not really fond of the font (just had to say that
) The big black hole on the right looks really crappy. And well, even though the background looks OK, I think it gets a bit repetive (same "texture" all over the wallpaper)
I wouldnt want to use this as my new background...4/10
