Wow... four years?! With my attention span I wouldn't even make it through the first! Over all this map is actually pretty good. The outside world could be worked on, but besides that its really good!
Actually, another bit of criticism would be the unusually bright lighting for a nighttime map. Not that making it unnecessarily dark is a good thing,. because it will quickly go from bright Cartoony TF2 to dark depressing Half life.
Still, nice.
