I want to submit my design, unfortunately the contest was closed

I will extend the design for a few more days

I have unfortunately received only 1 entry that can be considered. Therefore, I will extend this design competition for another few days. If you would like to see my own proposals for the first 3 walls, please check this link: https://www.dropbox.com/sh/bugahr1cl49d5rr/AABYXaUUz1iLO0Yp05k3o7nma?dl=0
I am still looking for a simple, elegant, and creative solution for Wall (6-7-8) and Wall (9-10).
