Pros:

Long different enviroment - european like CS maps
Good supply placement
New decals and sounds
Solid panic events and finale
Good length to maps - just about right
Very good lighting and atmosphere
Njoyable campaign
Very good poster
Cant fault the gameplay

Cons:

Some areas look out of proportion ie castle area
Some areas didnt quite flow right.
Few nav issues- as always more valve AI than map itself
Some of the window texturing needs lifting as it looks wrong that low.
Need to kill sound when radio playing music is shot :)
At finale if you stand on the trash bin, infected wont touch you.
Gotta do a widescreen poster!
Some asthetic structural issues

Conclusion:

Ive watched this campaign for some time and have seen it progress steadily. Overall its a top campaign, but to be up there with suicide or bloodtracks etc I think its lacking that little extra detail and refining. Some areas still look at bit blocky or not quite proportional. Some doors just look out of place , some rooms look structurally wrong. I am ofcourse nit picking as most wouldnt stop to look at details but I think its worth saying.  

The gameplay, pickups, sounds, atmosphere are all there though. Good job! look forward to the update
