Wow I hate cc maps. And that isn't a reason to rate it bad.
Looking at the single screen shot I can see no valid approach point, and at least 9999999 camping spots.
I realize you were going for small & fun arena type thing, you need to also do your best to avoid llots of camping spots. The problem with smalls maps is just that. However de_cs2d does a great job of preventing that. The camping spot in the middle is reduced because the CT can flank them for the opposite ends of the map.
1 it's too small for that
2 why do you need windows? noone would go here
3 why are there weapons on the floor? tactic = money = buy weapons (needs winning on first round etc)
the map itself deserves a 3
