Producing a warmer image
I try to always stay close to the mood I want to go for in my image, linked to the idea. Here, I think it would be nice to have a sort of warm desert planet. For this, I use a Color adjustment layer, and add more red and green to the shadows. I do the same for the midtones. I also use a Hard Light layer, on low Opacity, with a warm orange. This layer is then erased to leave just the top of the image more orange than the rest.
