A couple of months prior to actually executing this vision, I had a sudden idea of trying to make these kinds of arches and use them in a map.
The reason I thought of it was due to my previous success with the "RibCageRocks." These assets—whilst a lot more simple—were essentially just to test out an idea. I just needed a kind of push to try it out.
This is where CryptoLadyGabi's art piece: https://x.com/DreamyGabiNL/status/1763118380150640918 entered the process, prompting me to finally give it a try. The composition came naturally and took extremely little effort to get right.
