I like it, love the whole sonic idea lol the color tho would make my head hurt after a while but that's cause my eyes get sensitive with bright colors, i like deep mood tones myself. But I love the pic!!
I basically use 800x600, have a desktop very cluttered. using a FFA wallpaper... My print screen has some problems, cannot show the pic...
1024*768 This screenshot of GTA: SA is my favourite. The night, fast car etc. I hate abstract wallpapers, they'r so boring. This is the wallpaper is usually use: http://www.deviantart.com/deviation/18994684/
