I'm agreeing with Berry here.
This map looks like it's still in the planning phase and there haven't been (m)any alterations to it at all. The map looks like, and could still use, some height variation, prop placement, dynamic areas, lighting alterations, etc... I'd write up a review but the problem is there's nothing really to write about. It's just an uninteresting unfilled box with working control points, and... that's about it, really.
You should try to at least be satisfied with the layout of one control point before submitting an A/D map because of how they work.
Don't be discouraged, though, OP, because you're not the only one who's made a map like this.
