That sniping. Mid is impossible to do shit whit sniper. no good angles, only that door at ramp, and event that is not too good. It takes time to learn class balance.
Next is sides of map. sniper is perfect to area that is no use to defend. Maybe wall to middle of this "hallway".
Engineer is not best class at koth, but after all mid has only one good place to minisentry and regular i couldn't find any good place.
map is too short so teleporter will be useless.
this was interesting. Only scout is able to jump over this small box. Maybe some wall to protect everyone who uses these boxes.
I don't know that do you know that heavy can jump up here. interesting. Keep it.
this corner is useless and looks so sad.
there is nothing. Maybe that are should just shut down.
After all this is good one to a first map. takes time to learn mapping and I hope good time whit map making
