City concept for a fortress city built high in the mountains. Let me know what ya think!!

Hey folks, so a couple of years ago, definitely post pandemic, I downloaded a free concept art course that focused on digital painting and using z brush to create reference images. For life of me I can't find it on my computer and I can't remember how I found it. I remember that the creator had a website dedicated to it, and had an explanation on why it was free. About how they wanted to a force for change in the world and there for was giving it away. I also remember it was large and I had to torrent the whole course. Can anybody make me feel a little less crazy, lol?
