This turtle is in a dreamy, sparkling world! Its diamond-shaped shell reflects the twinkling diamonds of the planet, and the rings orbiting around it add an extra layer of majesty. The contrast between the dark turtle and the glittery background will be sure to make any finished piece pop. To provide a vivid contrast, try a lime green or magenta for the turtle - these will also provide a nice balance with the small diamond accents on the shell. To enhance that ethereal feeling, consider experimenting with blues and purples for the diamond planet and rings. For an extra special touch, add some metallic shades for an even brighter look!
