Esthetically, absolutely stunning, this is why it hurts to say that I am not really feeling the map gameplay-wise.
There are some spots where you can stand ground, but kiting (HoE) on this map is just not possible with all those small little doors and ramified (lot of corners for zeds to spawn) passageways. The way from the train yard into the mansion is one of the biggest no no's so far. Also, the trainyard in general looks really weird, especially that little passageway which leads to the backyard. An idea for the train yard might be to open up the empty area behind the train yard (towards the tunnel) for a new and bigger area which leads to the house (mansion). This might offer some kiting possibility then as well.
This is really the only thing which differentiates your map from the official maps, imo. Tripwire's maps all feel bigger and less clustered, offering the possibility of playing two different playstyles.
