Pros:

Great Fun to play
Good attention to detail
Smart use of Lighting
Good variety of areas, outdoors, cellar, and the bar
Zombies come from all directions

Cons:

Outside is a bit boring
Some fog would add to the atmosphere

Conclusion:

This map is brilliant, I loved the crashed car and got burnt by it when it set on fire. I also like how the battle bus is positioned so the light shines through the doors, very atmospheric. I'd recommend you download this, clearly a lot of thought has gone into the design, and it's competently made.
