Need some input on my map.

Hello to any and all forgers.
I have just completed a map that was designed for Strongholds, Neutral Flag, but could work with basic Slayer. I am currently at a point where I have it 80% done where the last bit is just filling it out with weapon, extra cover, and maybe one more small building.

A crucial point that I need help with is connecting to parts of the map together in a natural and fair way.

The map is called Black Castle and I have it bookmarked but I have a lobby open right now should anyone want to join.
