I downloaded your map and i'd like to give
you my opinion. I hope you'll learn
something out of it or at least get some ideas =).
Positive: I like the way you designed the map. At first , the windows were
nice made. Also the bunkers had a nice style.
Negative: The texture on the roof of the bunkers was... horrible.
No way that you use that kind of texture in an aim_map.
Also take a look at this picture .
Pay attention when you place your walls etc.
Positive: It's really a fun-to-play map. Camping will be inevitable on this map, but that could be pos. or neg.
Negative: You made the front of each bunker without any windows. I think it would be better With windows there. (My opinion)
Also : Pay attention for spawnpoints! You placed them so players could spawnattack eachother when freezetime's over!
Lightning could be better ...
Add windows at each side of the bunkers.
Fix the Floor not sliding good in eachother.
Other texture for the roof!
And another great hint ... Keep it up buddy! I really can see that you have good enough skills to make good maps.
Exercise , exercise , exercise...
