Apologies for the generic screenshot, MediaTracker goofed up the screenshot I was taking.
After playing around on a few maps and with the level editor, I finally decided to make my first full-blown SM map, and this is the result. I went into the map editor without much a plan, save for the idea of having the goalpost on an "island" of sorts. The map is wide open and claustrophobic simultaneously, depending on where you are on the map. There's a few ways to approach the goalpost, mainly through a set of launchers or by jumping from some raised platforms.
Plentiful Spawns
Sniper Decks and Tunnels
Offzone "Moat" around the Goal Post
Have fun with this one!
