I've been running around the map and made some notes:
There are no walls or props marking the border of the map. It may be small, but you've put a player clip at the borders and expected to reach the skybox.
This is a big problem: you can see the spawn exit at the top of the hill. Expect to see a sniper up here scoping right into the spawnroom.
Remove the ladders, too confusing for new players
Now being serious, I've shot that prop and it appears to have a box-like collision mesh. So bullets and other projectiles can't go through the gaps.
The capture area is unmarked and rather small. You should mark it and make it a bit bigger so it isn't as big as the control point prop.
One one side we have a health pack, and the other an ammo pack. For balancing purposes there should be only ammopack/healthpack or both.
I've only got on that platform via rocket jumping, and it leads to this:
Another spot that can look the spawnroom doors, but this time it's higher.
I tried to get up there rocket jumping from the outside but, of course, I failed :I - This could work as an alternate route to get to the point, but the only way
I have some suggestions on how to help the things I've said above:
It basically follows the Viaduct Formula, and it should separate the map in spawnroom-courtyard-mid i think it goes like that, never knew the names
But if you can come up with some different "formula" like Nucleus does, feel free to try it out!
