Inside Tiles
 

Those are pretty nice, I like the detail on the doors. But they change in height?

Hmm it's just an example of the expandability of the tiles.

Could be one of those small doors that lead to basement and small storage areas and etc.

Hmm, the floor pattern's perspective looks a bit weird, as it seems like you're showing the top side of the floor board that's coming up?
Maybe flip it like this:

I like it. But the only thing....the walls have a pattern thing...and it looks unnatural...the color blending I mean
