Here we go, this is my first wallpaper. This is the famous Jackson Rhandy Rhoads guitar!
It's a little bit simplified, of course, to make it a little bit more "cartoonish" and better-suited for a wallpaper.
I usually set my background to #b8b8b8, but a lot of different colors can be used.
I'm using this wallpaper on my desktop since a lot of time, and still I haven't grown tired of it.
