Pros:

Well detailed
Nice lighting
Enjoyable

Cons:

Smallish survival map, cant go up on roofs or other levels in buildings
"Diner" sign on what appeared to be a warehouse
You feel "Boxed" in, the barriers form a small square which you play in

Conclusion:

 It is clearly evident time and effort has gone into this map. I found it to be enjoyable to play and was worth the download. Keep up the good work!
