I really had nothing in mind but what I knew was that I wanted to make an environmental scene! Here are the images step by step of how I built it. Sorry no video process, but I really had nothing planned in mind :)
1. After putting basic shapes on a Multiply Layer, I started to define and make something come out from those different values I had. I mainly used a Flat Hard Brush with full Opacity.
2. I merged down tha first layer with the background and created another layer (Overlay mode) and put in the main 2 colour values. Cool and Warm.
3. Went in more definitions and shadows / highlights.
4. The finished product after refining the focal point and adjusting small details.
