Ok, your getting better, starting to look like real areas.
First Map: Still a little to empty, i know with that tileset there isn't really much you can do, but try and find something that can go on the ground you know, just to bulk it up that little bit, and you can put more things on the walls to.
Second Map: Getting better, but it seems a little to empty with the nature, try adding some grass tiles making some random grass movement.
Third Map: Like the second map, it still looks to plain, use the grass tiles more, and add broken trees or mushrooms or something.
Fourth map: Looking ALOT better, the burnt house is definatly looking alot more realistic, but that door, it's completley un-scathed, no damage what so ever XD how does that work? :P and again, a little more Fauna. Not to much as the house was just burnt down but ya know a little more. Also, where the path ends in the front of the house, howcome the fire just STOPS theres still grass around that path, it seems a little odd that just the house and the fences were burnt (not including the burnt things inside the yard) fire spreads, and it can jump just by a few sparks ^^
