Yeah its got nothing in it. Try not just using filters.
Looks very unprofessional. One tip, try adding some images in, maybe a varient, most people dont use anime wallpapers because they lack originality and themes, so if you want people to use a wallpaper, try and make a image people make y think will be original or maybe something that will look attractive. Remember, alot of people use winxp too, so the colors are usually blue, thats why you have alot of blue wallpapers
Hope this helps.
