Nice, really.
I love the shape, the colors, the way you understand the meaning and the corrolation with the title.
Also, the man in the center has a strong predence, despite his size compared to the picture.
I was just wondering about two questions, if I may ask:
-How did you came by this idea? Was it all of a sudden, or something you wanted to draw since quite a time
-What does represent the blending of colors, from cold colors at the bottom to warm ones at the top?
Anyway, good job, and keep drawing ;)
