I'd like to give some advice/criticism. Things might've changed since I was last on so please inform me if any of this is wrong.
TerrainI came on and looked at the map awhile back,
It was huge, and very well done for it's size (aka not cubescaped or on a grid), although it was extremely flat. The landscape literally did not lower or raise more than a few bricks a any point. The actual dayz map was extremely hilly and had some mountains.
The terrain is well done but not very interesting. If you are trying to replicated Chernarus (I assume not.) then it isn't a good copy. If you are trying to make an original map add some canyons, hills, or mountains. It makes it a lot prettier.
StructuresThe houses in the towns are neat and I like the blocky style. Unfortunately they don't look look like they are from a zombie apocalypse. They are in perfect shape, not torn up at all. In a real zombie apocalypse, the buildings would be burnt, damaged, old, or unstable. These houses are in perfect condition.
It almost looks like a bunch of zombies were dropped into a model city.
They also don't look like people have lived in this. This is the problem with a lot of games. The houses don't have furniture or signs of humans. They don't look like anyone ever lived there. This is a problem apparent in DayZ as well. 
The houses are well built but the interior lacks quite a bit. Make it look like people lived there. Add trash, furniture, or rubble. Don't just have the loot lying around on the floor like in DayZ, actually store it somewhere it belongs.
Design (In general.)I think it's got an extremely unique style that fits DayZ very well. I'm not sure how well the mod will turn out (Things on this scale don't end well as torquescript addons) and I'm assuming only half or so of your planned features will be created. If you need any help I could send you any of the old North scripts to try and work with.
I think the towns are extremely well layed out and in ways that actually make sense. You can imagine people wandering around the streets. The map (as a whole) seems slightly flawed though.
The way it is currently layed out (or at least when I saw it) wasn't curving and couldn't be an island. It can't really be finished. You can't have seamless borders how it is currently set up, like an ocean. I'm assuming if a player wanders off too far you will do some kind of Call of Duty "Return to the battlefield!" sort of thing, but that really takes away from the immersion.
I also don't like the fast that the 4x4 cube "bushes" have collision. It's just a small thing, but it would be neater if you could hide in them.
Overall the entire thing is very cool and much better than I originally expected it to be.
Also to Spectrum2: here's a screenshot I grabbed of one of the farms outside of a much larger town:
