I did a breakdown of this project for 80.lv
https://80.lv/articles/closed-off-interior-space-production-techniques/
This is my entry for the Artstation Beyond Human challenge that I made between July - September 2017, based on the concept by Ilya Dykov : https://www.artstation.com/artwork/eooBG
Had lots of fun working on this and I learned lots. For a long time I have wanted to make some more closed off interior spaces. I felt that most of my previous work had been outdoor open spaces and doing interior was a way to tread new ground and further expand my skills.
