Pros:

• Looks decent.
• The armory is quite well arranged, relatively easy to grab guns.

Cons:

• Rather a small map, although considering it as "alpha", it's understandable.
• The water in pool area and the soccer doesn't seem to work.

Improvements:

• Fix the issues with soccer and pool.
• Consider changing the climb textures a bit and possibly making it a bit harder. You're also only using half of the current climb area.
• On the roof with the AWP and cardboard boxes, it's rather difficult to jump on the boxes, hence difficult to get on the roof. Bad collision detection.
• Add more activities.
• Light is never 255 255 255 (white). Change your values down a bit and add world space glow.
• Rearrange the positions of some areas. The LR area (guntoss) and climb seem less ideal than where they could be.
• Add a few more cells. 8 + 1 doesn't seem much.
• Add a way to access the armory again. Some triggers for CTs approaching the door would be nice too, instead of pressing a button to open it.
• Add a logic that will automatically open the cell doors after X seconds.

Notes:

• I couldn't find a purpose for this button here next to the armory: http://i.imgur.com/jwZWv.jpg You should also make it more flat or fix the sides of it.
• I couldn't find a good use for the showers either for other than asthetic purposes. You could merge them to one too and move from the back of the pool to the side or somewhere.
