It depends upon what kind of game play you are trying to generate, but my gut instinct says that the strat targets are grouped too tightly. That may play into how you expect the map to be played, however, and may be by intent.
For what it's worth, I'm kind of hesitant about giving my opinions on other peoples map ideas, for three reasons:
The first is that I'm only just working my first, and I sure don't consider myself an expert...
The second is that I've never played the ground war, and I don't know as much as I should about that before I go offering advice...
But mostly, it's this: One of the things that I feel is that all the maps currently in rotation are mostly far more similar than they are different, such that for the most part each one kind of feels like a lot of the "more of the same ole, same ole".
So I'd rather see you (and everyone) do something "different" that I wouldn't do, so that when all our maps are in play, they have an entirely different "feel" to them, and create a sense of variance that (I feel, at least) is largely missing. For the same reasons, I've avoided asking for any input on mine. If we all go with the consensus opinion, what we'll all end up with are maps that are a lot the same.
