Man, I just love the "weight" of the scene and the consistency of the textures! Keep at it!
I like this! The only thing that jumps out at me as "wrong" is the any of the door ways lack depth ... the walls appear just pixel thin instead having the inner dimension they need! Aside from that though I think this is really good!
This comment is for the four tilesets you just added. All are very well made and while I am not a fan of over-pixelled floors on isometric tilesets they are wonderful.
Oh. didn't comment on any yet, but this is my favorite :P! Amazing work!
