You need to place healthkits and ammo packs, the resupply locker in Blu spawn doesn't work, and you need to clip the stairs going down to the mid area (the ones on the left of this screenshot)
Also, the pit of gold is clearly a clever comment on the materialistic nature of humans, because once you've been drawn in by the promise of gold THERE IS NO WAY OUT.
Other than that, the map's layout was good and I had fun playing it
Edit: You also need to make the step up on the floor of the base less steep so players can get up it without jumping.
