It's a nice map
.
Just the layout could be more inmersive. (The terrain seems a little too squarish, and it feels like its not part of the ground, also the map itself feels like a box, it lacks of background, it doen't feel natural)
The other detail is that there are too much boxes. Why are you spaming those boxes? if the boxes doesn't serve to a gameplay purpose, its better to not put them. Some boxes are fine, and other are just filling the map or simply blocking the players.
Anyways its a good map, but could be improved. I think you have good skills, keep the good mapping!
