Invisible Cities: Argia Building Development

Since I was still not satisfied with my buildings, I decided to research how some other artists drew rocks. I came to the conclusion that I didn't want them to look too boring/blob like, I really think that having them more spiney would look better. However, to distinguish between the generic buildings and the hero building, I made these ones look less uniform/organised (an idea that popped into my head while refining some column ideas for my interior. I'm pretty happy with how these look, it sort of reminds me of an insect nest (like Shelob's Lair from Lord of the Rings) but I think it still looks rock-like and menacing.
