Some comments on the inside level... Well the walls seem strange, since it's like you're looking at it from a fisheyed topdown view. I don't think that view is possible at all. All 4 sides of the walls wouldn't be seen equally like that, but oh well... Secondly, change the floor border to something more fitting.. (that purplish brownish thing that surrounds the floor tiles and goes around the wall)

The blue on the pots needs it's contrast turned down. The color saturation is way too high. It makes it look like some blue ring that is floating around a pot. If you fade it a bit, it will look more like a painted on decoration. Also, if you insist on using that red carpet, at least turn the saturation down on that as well... something a little less bright and vivid, as it's totally clashing with all the other tiles. I like the floor and bookshelf though, they seem a bit better quality than the other stuff.

The outside looks okay... Although I agree about the bush thing and the sign. Good job overall. Much better than most tileset modifications.
