As for the stories, it's simple at first glance yet become somehow meaningful when you re-thought about it. And it just hit-the-spot. It has a great concept with good execution. I think I can see the way you merge the optional theme decay with the limitation buildings in Tatemono no Omoide (sorry if you actually didn't merge both the theme and the limitation).
As for the arts, it's classic, kinda ambiguous (only few), and are really really a good one.
As for the music, it's moody, balanced, fitting, and not overdone.

I think I can see the way you merge the optional theme decay with the limitation buildings in Tatemono no Omoide (sorry if you actually didn't merge both the theme and the limitation). It's interesting and unique. I love all of the stories. And it's kinda hard to choose one. Although it may looks like that my favourite one is Tatemono no Omoide, I do prefer Hanami.
And below are my understanding about Tatemono no Omoide + the relation of the theme decay with buildings that I think it's connected. Since I'm interested in it, please provide your thoughts as well. I want to know how others interpret it.
[Spoiler alert about Tatemono no Omoide]
So, it seems that the spirits lost their home (apparently some lived on a tree, near a stream, and on a hill? And as for spirits whom lived "on a tree" I interpret it as : in the woods). And since those trees and hill get replaced, the spirits "decay" and became the "buildings" as to replace their home. Or, their home are decaying and so, the spirits chose the buildings to became their home.
And yeah, I write this at 1 AM. So, I kinda lose my focus. And sorry for my bad grammar or the potential "it doesn't make sense" wording.
Anyways, thank you!
