I always appreciate items that make a scene more like real life such as food items (I don't think I've seen fried chicken anywhere), bric-a-brac that clutters furniture tops (lamps, vases, books, jewelry boxes, piles of mail, etc.), and stuff like that. You can have a really lovely bathroom with great tiles and stuff but it looks much more realistic as a scene if you have towels, toilet paper, soap, etc. so that it looks lived in.
