Erk your map shows good potential, it looks quite nice without being over detailed, what game mode is it?
Nitewalker, that payload map looks quite good, but the pit in the second photo looks quite annoying to get out of, perhaps add another ramp on the right side? Also the last pic has a big choke point on it, now this is not necessarily bad! Especially because I see a good side route, but consider adding another to the left side of the choke (forgive me if i can't see it). Also keep in mind the payload will take up a considerable portion of that choke, but this can be used as a game play factor if you balance it with good side routes and health kits.
