About this design

What the design shows

The Clean artwork centers an ascending koi in a long S-shaped turn, with its head lifted toward the upper right. A rounded forehead, one clearly visible dark eye, a compact mouth and a curved gill plate define the head. Fine whisker-like lines frame the snout: one sweeps outward while a shorter curve sits near the crown. Overlapping scales follow the bend from shoulder to tail, with pale centers and darker rims that give the body continuous grey depth. Broad, ribbed fins fan away from the body at several points, balancing the narrow waist of the curve. The lower end opens into a complete forked tail with two separate flowing lobes. The image uses monochrome black-and-grey realism, selective scale texture and a consistent light direction. In the On-skin preview, the same vertical koi follows the forearm, with its raised head toward the elbow and tail toward the wrist.

Placement

Placement and size

The On-skin preview places the fish vertically along the forearm, with the head nearer the elbow and the forked tail pointing toward the wrist. This orientation lets the eye follow the full S curve while keeping the side fins and tail within one continuous panel. The Clean design has a narrow waist and broader ends, so an artist can check how its curves sit on the arm's natural line before settling the stencil. The calf is another area to discuss if a similarly upright presentation is preferred.

Patchwork

Building it into a patchwork

The long S curve gives this piece a clear vertical direction, while the head, open fins and forked tail create three wider points along its silhouette. It can anchor a cluster of smaller motifs arranged beside those wider points, with a few compact marks near the narrow middle. Keep neighboring outlines clear of the fins and tail lobes so the fish remains a continuous form. Its shaded scales carry substantial visual weight, which can balance lighter outline pieces elsewhere in the group.

For your artist

Notes for your tattoo artist

01Keep the raised eye legible inside the shaded head and preserve the mouth contour.
02Retain the long outward whisker curve and the shorter curved line above the forehead.
03Follow the body bend with continuous grey transitions rather than hard bands.
04Keep the forked tail lobes distinct and the rib lines open at stencil scale.
05Use selective scale texture so the mid-body stays readable through its S turn.
