I love the basalt cliffs, and I admire how you (I think) put in a nearly imperceptible waterfall where the river drops into the gorge. It looks like there's another river valley coming up just around the bend (although I will for that it could have run or may be entirely dry), but, if not, I would think that it would be the logical place to put a town, because then you could hike up the river and climb this cliff and seek spiritual guidance from her.
I don't actually create the models, they are all commercially available components. I use DAZ Studio to import them, pose them, and light them. Often I mix and match the outfits as well. The base female model is quite flexible, the majority of my images use the same model, with many many character variations. And clothing and hair variations. I also use Photoshop for the postwork.
