I think both collages have managed to capture the essence of the houses. Without knowing the name of the houses would be a little difficult to know which house relate but I think its a good job of expressing the story.
I like their simplicity of them a lot
There is stability in the second one. Would be better add a dynamic element.
I also think that at first view is quite difficult to know which house you are talking without knowing the name, but the collage itself is very nice
