Here's some quick thoughts based on the screenshots:
1) The map seems pretty much like a box filled with stuff here and there. That's not good since it limits your ability to do something more versatile.
2) Very open and barebones, there isn't like paths and areas where fights take in place, just a yard with a bit in the middle.
3) The hatch needs waaaay more space than being shoved between two tall walls with only two paths to it. Hatches are almost everytime outdoors and with a fair number of open space and pathing.
