Pros: A great idea, and - finally - we get some honest to goodness bird's nests for the snipers to play in. Jumping into them as a Demo or Soldier is also really fun.

Cons: There isn't enough to the map to make it feel like a real combat environment. Elements of it, such as the scaffolds and cells inside the map, are so cheaply thrown in there that it feels like you're playing inside a shoebox, between a pair of boots. The second portion of the map also starts off ridiculously unbalanced, and if the attacking team doesn't take it within a minute, chances are it's going to be very hard to get out of the gate from that point on. Especially with skilled snipers perched on the defense, and the requirement to activate your doors each time you want to attack from behind them.

Improvements: I would start by creating better scaffolds for part one, and adding more brushwork to the overall map. Make it look like someone knocked out a few walls inside the cells, and allow players to fight around in an intertwining group of hallways "dug" out from the sides of the prison. You can also use a continuation of this concept for part two, to provide some sort of underground escape route to the outside to compensate for the lack of any side exits. Also, take your time and place some props around the map. It's a war zone outside, right? Add some small debris, and some large chunks that can be used as cover.

Notes: I think the author should take more time with each section of their map before claiming a final release. I know you wanted to get it out there... but there's so much more that can be done, so why rush a final? We'll still play Beta! ;) I also think, if you do go back into this map to improve it, that you consider a third level. Think: Cellblock -> Cafeteria/Warden's office -> Yard (nighttime with spotlights.)
