You have done quite a nice job on this map.
I really like the way you organized the crates elevation using outline colors.Really functional.
One, or two questions: how high above the ground level is the catwalk supposed to be cause I can easily imagine a character taking a (nice) fall from up there.
Also do you mind to explain how is somebody supposed to enter from the east.I imagine from those things with the number 8 on them that must go underground or something but I'm not sure.
Finally, to stop rabbling I have to say that this map could easily find use in a stealth-based campaign.Repped.
