A ready-to-use 9:16 JSON prompt for an authentic black-and-white manga ink portrait: an original anime woman with a voluminous messy high bun rests her cheek on one hand in an oversized black sweater, gazing sideways. It calls for intricate ink linework, fine cross-hatching, soft pencil shading on the face, white-highlighted hair strokes and a pure white paper background with a tiny heart doodle, plus a negative prompt that keeps out color, 3D and photorealism.
