Pros:

I loved the school and all the little hidden files and stuff, plus the chalkboards have awesome backstory.
A lot of different paths and the gym was a suprise.
There was some very funny graffiti in it, which is rare and much liked by me.
The school/evac center was my favorite map.
It feels like its a -improved- valve map, so kudos there.
The graffiti had a feeling of it being fitting for real life in it.
It has great re-play value.

Cons:

There could have been more note's, and some of the chalkboards was hard to read plus some at the school could use some stuff on them
A few areas was a little dark, but not pitch black.

Conclusion:

I loved it, and althought i havnt played it in VS yet it seem's to be fairly balanced from what i saw while playing thourgh it, and i had a blast trying to track down all the hidden files and stuff i dragged the game out for almost two hours just to find everything, and yet i dont think i did. I love it :D

Also CreamPuff, there's audio easter eggs in it?

Pros:

Very detailed 
The infected had decent pathing systems which is rare for some maps
All the maps was lovely
You scattered guns and everything out evenly
I loved where some of the Witches was located

Cons:

Its a tad to dark in some places
The finale has a catwalk thing above it, which would make for a interseting area to try it from if it was made accseible
The windows wasnt breakable by infected, which alas means no charging people outside :(
The gun cabnits in the mall should be openable in my opinion.

Conclusion:

I loved it, and will most likely re-play it a few times, I loved how the wind blew you of the helipad like it would that high up in real life, And the layout and forethought and skill put into this map was top notch, i'd love to see more from you :D
