Tell her she did an excellent job :-) I like it, you can definitely see the female "touch". I especially like the carrot for the horse, did she come up with that? It's clever.
A house with no walls is fine, it allows you to play and interact with the residents. Architecture isn't always as much fun as doing the interior.
The carrot was actually a set design, lol. But if I were to make a house with walls I'd have removable sections to enhance the playability.
