I'll just start off by saying I love the atmosphere! The green Combine lighting, and the shades of yellow to go along with it make it quite scrumptious to run around in. The rotating room in the center is quite a ncie touch, and I think you pulled it off quite elegantly.
-The floor textures and thought to layout of trim textures and the like makes this map look exceptional. each space seems well-defined by such simple attention to detail; -This is something I think other mappers could learn from.
-The round windows give a nice fresh view into other rooms, even though the views outside seem rather empty.
There was a nice door detail where you added a succession of fences to mark its importance, -very nice!
-Even the simple rotation of the radiator prop model seems to give some indication of thought to atmosphere when constructing this map. Little details like that I wish other mappers would pick up on. I think you've built a very well detailed map here. I could go on, but I don't want to ramble about things you already know. You're obviously an experienced mapper and it shows here. Congratz!
My only big crit is that even though there is a nice dome of clouds moving above the map, I wish there was something to look out into. i don't have a sense of surrounding while playing this map. -Where is it located?
-Nice map! 5 stars!
