Most of these are difficult to critque as portraits. In fact, it feels like you're aim was more toward making illustrative art.
I think you're really close too with the one with the ironing board. I like the symmetrical setting created by the arch, clock and radiator. I'm not totally sold on the pose, but I do like that you included homemaker tools in the composition. The lighting is totally believable.
I gotta tell ya... I really like your work. I wish this was in the general gallery, or even the critique gallery. This is pretty cool stuff. It should have a larger and more appropriate audience. Again, I feel this is more of a "illustrative" image than a portrait... where the maker is illustrating a mood or message.
