Map submissions have been taken away.It would be a much better idea to create the map yourself, and submit it so people can see what it would look like. If you don't want to do that, at least go into extreme detail about how the map would like, how pvp would play out, would there be caves, trees, water. You can't just say "make new map plz" because that gives no information. :)
