Awesome maps. Ofcourse,I would like to see a few things improved.
The run from Red spawn to Point one seems very long. It might be the equivalent of Dustbowl, but Dustbowl is a three-stage map, amsterdam is a one stage map. Making a "drop down vent" or something like that, which closes when point 1 is taken might fix this.
On the final point, I would like to get the "boarded" window opened up, to make it easier to defend, but I do understand the point about sentries getting destroyed too quickly then.
Maybe add a small sniper position on the top floow, in the small corridor furthest to the left. In addition to this, add a little more cover for the attackers (Nothing big, just somewhere to take cover besides the truck).
Improve the sky box a bit, eg. add cardboard boats, fix the "cut-in-half" house, etc. Lower the "roof" of the map outside, so that BLU demomen can no longer jump up and see down into the red spawn.
Make the crates in the BLU spawn climbable,so the BLU teamhas something to toy around on, while they wait for the round to begin.
The only thing that concerns me about the map are the very confined spaces. Pyroes have a huge advantage on this map, while scouts have a very hard time getting kills. Also, the map might end up as a clusterfuck when playing with 30 players (we have to test it to know

).
Besides this, I love the map
