I missed the chair and the kitchen, although in retrospect I'm seeing some indicators in both of them that I ignored. If you look closely at the metal on the key, fork, vase, and juicer you can tell which textures are repeating and which aren't. The car was clearly fake to me because of the overly clean tires contrasting against the systematic dirt layers around each wheel well. The portrait and the spider both were given away by bokeh, the eye by the texture of the skin and quality of the hair, and the peppers by the pattern and look of the dust on the table.
