A cybersigilism thorn-wing tattoo design in hairline black ink, drawn as a mirrored pair of wings on a central spine. Layered feather-like thorn branches fan out from the centre, with small sparkle stars at the wing tips, all on plain off-white. Replace the wings with your own subject or recolour the line.

A tattoo design reference sheet: a pair of cyber sigilism wings for the upper back, drawn in pure black needle-thin ink lines on a plain flat off-white paper ground. The design is perfectly mirror-symmetrical about one vertical centre line and spreads wide and low, about 85% of the canvas width and 60% of its height, with generous empty margin around it. At the centre a slim pointed spine sits on the axis: a thin vertical blade with small hooked thorns and a tiny four-pointed sparkle star at its middle. From the spine, each wing sweeps outward and upward in three tiers of long feather-blades. Every blade is a hairline stroke that swells very slightly in the middle and tapers to a needle point at both ends. Small curved thorns branch off the blades like rose barbs, and some tips split into double points. Smaller thorns and veins curl inward near the spine, while the longest outer blades arc out and then hook downward, ending in razor-sharp points. Lines are spaced openly so no two strokes merge, which keeps the design stencil-ready. Use only line: no solid black fills, no thick bands, no shading, no gradients, no grey tones, no chrome, no glow, no 3D. Add a few tiny four-pointed sparkle stars outlined in hairline near the wing tips. No text, letters, numbers or symbols. Flat even light, crisp ink edges, clean scan look.
