Hey I love your map, and when i played it and went ramp i realised that box could be done bigger and more curved so that when T's throw a Smoke, Flash or HE it will not bounce back at them.
I only really played on the ramp side of the map I think also it would be brilliant to add more wall bang to the map, such as you could totally wall bang entire Ramp.
Overall i love your map, hopefully you will read this 3kliksphilip :)
