Regarding the mutalid, I like the old one better because it looks less like a monster, but the new one's cool as well. I think they should both be used.
Regarding the new areas, here are my suggestions:
-Farm (see my Bluzone Forum post on the details of the farm)
-Motel (a 2-floor buliding with many rooms and a parking lot out front)
-School (I think this is already planned but...)
-Shopping Center (one room building (with maybe a few changing rooms or something) with a lot of shelves and stuff (clothes, tools, etc...) It would be necessary for survival with its supplies, but it would be very dangerous)
-Forest (I know you hate this idea but I'm sure I can make a great looking forest with uneven ground, tall trees, dense underbrush, a stream, and paths and stuff. Brick count would be my only problem, but I could deal with it if I tried. It could have camp sites set up too)
