Concept Art Project

This is my project for this class, a Dune-inspired concept art for a futuristic dessert planet. I included a structure as a space station or city with character designs that matched the other-worldly, dessert inspired look.
The prompts took a bit of experimenting and I had to refine the prompts at each step. Initially the images had a intergalactic look with space ships etc, but I wanted a piece that had more earthy tones, and was on the planet rather than in space.
Prompt for my final environment designs:
concept art or matte painting of a space station, with the image of a man standing in a desert landscape, in the style of spatial concept art, style of Dune concept art, columns and totems, mist, greeble, sharp brushwork, gigantic scale, sharp focus --ar 235:312
Prompt for my final character designs:
Character pose sheet of a full-body image of a young hero in an intricately designed desert-styled outfit, blending traditional and futuristic elements, set against a breathtaking desert backdrop with sand dunes and hints of gigantic sandworms. The costume features earthy tones, metallic accents, a flowing robe with a hood, weathered armor, and a dagger, creating an aura of grandeur, mystique, and adventure
These are the images I got back:
I felt the first landscape was the one that really matched the vision I had for this piece, so then I generated a widescreen (--ar 16:9) version of that first landscape, and that resulted in a similar image, but almost looks like it's from a different angle. Then I pasted the images I liked best into one document in Photoshop for presentation:
