HARMA: Sanctuary of Heart - Ideation & Design thinking

The ideation of atrium in a sanctuary, where priestesses gather and consume enigmatic resin from sacred tree.
It's continuation of a project I did year ago, where I designed characters connected to the environment:

I am separately uploading also a design of the Sacred Tree:

It's a project that I've been doing after work ~a year ago to keep creative juices flowing and get into AAA buuut... I got in before I finished it. Sharing what I have so far anyway, maybe in the future I'll update the project with next design steps! It's been sitting and waiting on my drive for a year now, and it was so lonely I decided to unleash it.
If continued in the future, I'd love to focus on basic playability of the environment and movement possibilities, for now, unfortunately only ideation.
I've decided to share it anyway, since design thinking is fundamental part of a concept artist job!
As always attached some notes and detailed descriptions in case if you were bored.
