Need advice and tips for my Halo reach forge map

I spent most of my Thanksgiving break from school making this map, which I originally began as a map to encompass the entire Forge World area, which quickly failed as every game played on the map lasted hours with most of the time spent traveling between bases, and the map was quickly shelved.

When I remade the map, I figured out how to make it gametype compatible, and made it compatible with Slayer, Infection, CTF, and Assault Gametypes (Even Grifball, in an amusing accident.)

When I showed the map to my friends upon my return to school, everyone seemed to love the remake, but somehow, their words rang hollow. While I appreciate the support from them, I feel I cannot consider it a true success unless I release it to the community and get feedback to help me make it better.

Here are some of the features:

Red and Blue Bases:

4-level bases, with the following weapons placed within:

Concussion Rifles
Plasma Repeaters (This was a tough choice, but I used the repeaters due to their not overheating as badly s the rifles)
Sniper Rifles
DMR
Assault Rifles
Grenade Launchers
Rocket Launchers
Spartan Lasers
Shotguns
Spikers
Pistols
Plasma Pistols

Vehicles:
2 Ghosts
1 Rocket Warthog
1 Normal Warthog
2 Mongooses
1 Scorpion Tank
1 Banshee (Located on the top level)
1 Shade Turret (Top Level in front of the Banshee Spawn)

Aerial Platform (Located in the air about mid-map, accessible by using Man Cannons):

Weapons:

Energy Swords
Gravity Hammers
DMR
Shotguns
Sniper Rifles

Vehicles:

2 Shade Turrets (One overlooking each base.)

In the middle of the Area (Underneath the platform), the following weapons can be found:

Fuel Rod Gun (Located near each teleporter that leads to the man cannons that go to the aerial platform.)
Plasma Launcher (Located near the central receiver node (What I call the bail-out teleporter useful for quick escapes from the platform for use in Infection matches or when staring down enemy banshees.)

Structure notes:

Bases: I designed these to serve as more fightable bases compared to maps like Hemorrhage. (And no, this map isn’t an edit as one can quickly see.) The second level can be reached through either going up the ramp to the third level and jumping down the hole or going into the ground level where there’s a gravity lift. Where you land from the lift, there is the flag spawn for CTF games. The Assault Goal and bomb spawn are located in the ground level, in front of the gravity lift. The third level has two parts: The interior, which is inside the 3 story tower that’s located on the back of the second level, and the exterior which is on top of the second level. The fourth level can be accessed be either using the Man Cannon that’s behind the base, or by respawning up there.

Aerial platform: I designed this to serve mainly as a spot for uninfected players to hide from zombies during Infection games, or to snipe down on the opposing team’s base.

The Giant Wall: During Infection games on Hemorrhage, I noticed that if the Infected’s speed was set to 300% and they Evaded up a hill, they could get over the wall. I took the same concept of the wall, but then added more wall pieces at a 45 degree angle to prevent such instances. The only way over the wall now is to jump from the nearby cliff. (also, there’s a hard kill zone near the tunnel to the island.)

I’d love to hear your feedback and suggestions for this map.

I feel like it is fine (in my opinion) as I cannot think of anything more then that to keep it even and interesting.
