First of all the map design and quality are amazing, I have no words to describe.
There are few problems though.

1. Not enough chokes points (choke point is where CT and T meet each other) there is just one huge choke point at the swimming pool, nowhere else for the T to try and go
There is a door right under the stairs, maybe make a way from T spawn to go there and add another choke point to second floor, and also one at the far side of the dining tables.

2. Make another exit from CT spawn towards that little room near B.
It's just a massacre to exit CT spawn, 1 door and then another door, annoying as hell, just make it double doors, it'll be enough I hope.

3. Too many objects are prop_physics_multiplayer and there are some objects who are supposed to be static but they are physics.

4. The pictures in A, if you touch them - they fall down and then won't let you move
To fix it just make them not-solid, many prop_physics in this map are solid and slow you down if you touch them, it's really annoying and can be easily fixed.

5. B has only 1 entrance from T spawn (for the 2nd one, you need to go through A, but then why would I go B, if I can just plant upstairs at A?) should add another entrance.

6. One way doors are really annoying (you can only open them in one way)
You can also make them open quicker because they open very slow.

7. You can get on trees near T spawn, but I guess it's ok (this is what they fixed on inferno near B site)

8. What's the point of a jet engine inside the bed room? =D

I can't think of anything else, but I really liked the map design you can just look and my steam pictures and see how awful I am at designing maps =P so you may also give me some tips.
Looking for the map's update ^^
