You got a nice setup. A lot of detail put into the game map which can offer some emergent advantages and gameplay rounds.
But when I say emergent, I mean that one of these TDM games are widely affected by what the map layout is. Things on this mapare more randomly placed based on kind of a realistic setup, and not a setup which combines strategic map elements with realistic map elements.
Tactical DM games come with a strategic map setup. People look forward to be able to piece together different tactics and game plans based on the elements on the game map itself.
Try adding some more objects to empty spaces (walls, barriers, maybe buildings on the outside of the center base to give an observing advantage for the attackers), or organize elements such as crates and barriers to add a strategic advantage for both teams in the game.
Otherwise, great work.
