Provided the screenshots are updated, I have this to say. Keeping in mind your objectives for the map, I want to point out that interesting geometry makes for interesting gameplay (it's not the sole factor, but it helps). Your map in the screenshots looks pretty square, so I would suggest spicing it up with some interesting angles/height variation.
I know this isn't the most specific advise, but it's all I can give from the screenshots. Good luck with the map, though
