Ubuntu 8.04 GUI Design Idea

My design idea for the new version of Ubuntu. I tried to go for a black/orange theme however it feels a little more brown than orange but oh well. If this is fairly well received then I might send it off to the Ubuntu guys to have a look at. I have seen some nice widget designs and icon designs around anyway so I haven't made anything new or innovative there... (Most icons are "Human" ones anyway). The wallpaper was just a quick'n'dirty curve things just as a place holder - again I have seen many good wallpapers in the suggestion boxes already.

Comments/criticisms/suggestions please folks!
