Hey Bionicle! So I decided to go ahead and have a look at your two first houses. The second one, as you said, is already approved, good job! But I have some feedback for your first one.
Firstly, you did pretty well the exts, I like the little working area to the right of the house. I left two notes tho, one for the crops on the yard and one for the flowers in front (this one more of a suggestion).
About the ints, I think it can improve a little, as they were feeling kind messy, so my suggestion is for you to try to think how the people living there would allocated everything, how would they walk around, etc. You have to find an equilibrium between occupying space and having space free. For you to better see what I mean I've made an example above the house with the same furnishing you used, just reallocated. If you have any questions, be sure to send me.
