My second battlemap ever. Finally got the guts to post it

The crates have outlines for height. Green = one level, Blue = 2 levels, Red = 3 levels (which leads to the catwalk around the perimeter of the third level where the "control room" is). There are multiple ways into the warehouse: The main door in the south west, the roof entrance (empty room) in the south east, and the loading docks from the east.

A glowing green vat in the center of the warehouse is controlled from some sort of gnome / goblin apparatus on the top level control room.
