If I were I wouldnt talk about your map and brain in one sentece. If you think your map is decent then you must think that spawninabox is masterpiece or idk. Srsly you havent done anything in your map what good mapper should do(I am not calling myself good mapper, I am just saying that i try to improve my skills fixing whatever someone suggests me). I really think you should look at chefs link
http://dplogin.com/forums/index.php?topic=5149.0 . You should have done it before releasing and not after tho.
Some feedback then
Cons
-Different sides, they are not mirrored
-Textures are not aligned
-Your brush usage makes nosense at all, if you make such a map then i would expect it to look like realistic, maybe its just my opinion idk
-Add "angle X" to your player spawn entity (X=number in range from 0 to 360)
-Learn how to use lighting in your map
-Try to be realistic, climbable brick pillar ...ok no comment
-Learn whats the difference between Face and Brush Surface (why is the pillar climbable from both sides when you can get up only when climbing one side)
-Learn whats the difference between qbsp and final export (just learn about all export options)
Pros
-Spawn with carbine
-Hm......uh..you used brushes in your map
Sorry for negative post but if you release this and then flame Rick for being noob mapper, well what do you expect. But still my Cons stays and thats what every mapper will tell you.
BTW:Blaa map names?
