This last part of the process was a lot of battling constantly the values, the last iterations helped me to find what I liked and what I didn't, when I had the greyscale I had my doubts on how to represent the different "demons" (War, tech/Ai, Global warming) But I thought I could work on that on the color stage. 

I tried also different color variations. I wanted to get away from the same color palette that I rely on most of the time. So pink was going to be the chosen one : )

These were the value studies that helped me to decide on the lighting!. And now... Onto the final.
