Hi everyone, here are a few ideas that sprang into my mind while sketching around. The two lower ones are particularly interesting in my opinion, I think I'll pursue those. As I'd like them to be really rocky, I'm not sure with which one to start first.
In the sketch in the lower left there are tower cities in these plains, and in the lower right there are towers carved into stone. There is a lot to learn about drawing rocks, and I plan to improve with the next few pieces in that department. See you soon with some lineart.
Best,
Simon
