Very nice map with a good flow and interesting height differences, especially around the "parlor" area. This is perfect for carpet bombing techniques!
However, it lacks a bit of ammo for 4 or more player games: even if there are a lot of spawn points. You should tweak a bit the "item count" item parameters to solve that.
Texturing is very very nice, except maybe for the big blue elevators. Shading is really nice too, but maybe differences are too subtle in some places (like the parlor ground)
The only real issue is with the over-complexity of the architecture which cause major slowdowns on netplays with many players. Using custom textures for your chessboard effects could really help there, especially for the "Parlor".
My first netmap. Harmonium is a small- to medium-sized map, best for about 4-5 players. It includes an embedded MML script for starting the player with the assault rifle and SMG.
The map is not terribly large, but at 844 polygons, it is very detailed, and may slow down for some players using OpenGL Shader mode.
I welcome any feedback.
