So here’s the vibe you're going for: Placement: Upper back, centered. Size: Moderate (not full back), enough to allow detail but not too overwhelming. Design: Yin Yang in the center. Two koi fish circling it (representing the Yin and Yang energies). Waves flowing around the koi, dynamic but elegant. Some of the wave lines or flowing water trails subtly reaching up the spine and into the lower neck — thin enough to peek from under a shirt. Style: Classic black and grey, clean lines, soft shading for depth.
