I agree with this.

I agree, the boxes seem a little out of place, and detract from the realism of the map. I like the idea of having something to block off the outside from ct-spawn, but feel that the stack of crates are a little botched, and they don't quite look right. Also the thing I most like about csgo is that nothing has one soul purpose in the game, the boxes just outside ct-spawn are good for dm for example, but the stack you have added isn't even climbable, and seems otherwise pointless. I feel you could do more with this at some point, as of yet I have no ideas, but I am not a map maker, so I don't quite know what would be possible.
Again the crates inside of ramp seem a little botched as well, as though you have had an idea of what you want to do, but have simply spammed crates to fill the area. I understand this could easily be a step to step thing you are working on, but I dont think that many crates is entirely necisary (if that's how you spell it).
But I love what you have done with b-site in particular.
You have definately got the right idea with outside and a-site but it seems a little samely. Maybe a bit more could be done to make it seem a little less plain than just the exact same repetitive boxes and storage units all over the place. That is why I like what you have done with B so much, because it seems less bland, and more thought out.
I will continue to play on the map, to see what I can make of things since obviously, I'm a little vauge atm.
Great map though otherwise, 8/10, more could be done, but you are deffinately along the right lines.
