This image is a studio in color an composition. The notes create a Fibonnaci spiral and the guitar is in the bottom right focus point in the rule of thirds. About the colors, I wanted to try some really saturated and strong ones. Red and green are complementary and they always work very good.
This image is an effort to start creating more interesting renders while staying in the photorealistic spectrum.
I hope you like it, tell me what you think about it in the comments!!
