Looks quite nice, but the map location is just bad. Why not integrate it with the upper right part of the HUD?
Edit: On second thought, it does make sense to have the mini-map where it is, as that's the most likely location of the player's units/location, and it wouldn't be too good having a significant portion of the screen blocking the enemy's location. But, as the above reply says, it blends too much with what's going on in the screen... maybe a thicker border would help.
This game just looks like a lot of fun to me. Doing my standard GameFly rental with it and I'll purchase from GameFly if I like it. My own version of try before you buy .
