If you would to submit a wallpaper to be considered for Wallpaper Of The Month, there are only a few things you must do
1: Make sure you wallpaper is of the proper dimensions, 1600x1200 for full screen, and 2560x1600 for wide screen.
2: You need to submit both a wide screen, and a full screen version so that anyone can use it.
3: Post it in the WOTM submission area of the forums, with the title "WOTM submissions for (e.g August)"
4: Post a thumbnail of the image, and then the link to both sizes of the image
5: Voting will be held in the last 10 days of the month, so submissions must be in by then.
Other than that, there are no limitations, you can make what ever you want, as long as it is not offensive. You DO NOT need to make both Gnome and KDE versions, if you want to, there are alot of users who would like it, but it is not necessary to be considered for WOTM.
So let's see some artwork.
