I think there is a architecture genre. There is an environment genre and one for nature. Landscape/terrain seems like a good idea since I'm not sure what environment means (not sure what household means either). I'm not sure what to do with graphics that are mostly interiors of rooms. Those aren't really still lifes, are they, but what are interior without people in them? Are they an environment??? I'm going to give up on genres for the night. My head is starting to hurt.
