Not too shabby! In the circled red area, nothing really happened, no fighting and no point in red sticking their noses here. I would suggest converting this area and the building in to open area, and push the building up to the blue area (with the circly bits being doorways).
The pink is meant to be a mid ground, not quite as high as the surrounding high grounds, but not ground level.
I don't have any gripes with this layout, it works okay, but the point definitely needs to be made more exciting. I'm not too happy with the area out of red spawn, so many of those silly gates, and all those stairways. Get rid of the stairs there, and put them connecting the ones next to the point.
I made the red overlooking building with windows, I personally would make them solid. I also would have a wall/fence at the bottom of the stairs to provide a bit of cover both ways.
I put a question mark for the blue route to the left, as it's just a suggestion; if you do implement it, I would say you don't need that back route. It's quite an advantageous area to have, so I think it should need some risk getting to it.
