Resolution is not gunna be acceptable.. use imageshack.us to upload your image

Yeah, I just registered on Imageshack about an hour ago, since I figured I would probably have to, but I just wanted to post it here to see what people thought of it, and what I could do to improve it before then. Here is the same wallpaper, but on Imageshack now. Also, it has to be a .jpg, right? I'll need to change it if it does, since I'm in the habit of saving images as .png.
