Hey this isn't the wall that you were working on Session Zero - lol!
Like what you've done here. Don't mind the white bands at all, I personally like those widescreen feel think makes things more interesting and help direct focus as well.
I like how the character is dark and everything else is bright - though I prolly wouldn't mind the middle band being a bit darker just to help bring it out more against the white bands and to tone down the overall wall brightness a bit. Just a personal preference.
Great job - congrats! ^^

Awesome wp! i would say this is the most unique wallpaper out of the bunch in the category. amazing colors. really like the japanese letters. great work! :)
