I like the idea of this map, keep in mind it's quite different and that always keeps people a bit reluctant to trying new things. However as for how to improve it:

Think the main problem is with a lot of the exits being way too narrow that often makes it kinda pointless going there. Also the top bit is kinda useless, I guess the idea was to have that space being more open to make FC's the incentive to go there to have more room to operate, but in the end people just goes straight as it works better anyway.

Perhaps an interesting idea would be to have more corners and small walls in the middle rather than the big one (like market), but with different end zones than market. The end zones with the bombs I think are alright, altho perhaps you could introduce some changes so those bombs have more potential uses than the current ones, which are pretty straight forward.

Also not a fan personally of the big space with team tiles in the middle, think those should be more situational, not something that gets used for virtually every play.
