In this 3D project (Blender+Cycles) the concept was to create an abstract organic shape from mathematical formulas (obviously voronoi). I was exploring the impact that lights have on the resulting colors in this "glossy" material. By the way, I also worked with DOF with the camera lens. 

To finish, the last touches were made with Lightroom (shadows, clarity, coloration, b/w) and Photoshop (brightness, levels) to clean and intensify the colors.
