Sorry for the late response. A good resource for learning more about color and light would be “Color and Light” by James Gurney. This one was super helpful for me. But other than that is doing lighting studies from movies or even doing some lighting exercises from life. Good luck!

I like this very much, but can’t express it with words very well. I think it’s first the earth tones, then it’s the subtle shading and lighting.
I would like my stuff to look more like this. Can you recommend any resources?

Thanks for the tip.
