Portrait anime

Generate 4 independent 9:16 images (do not stitch into one): Ratio: 9:16; Style: Japanese indigo dye shibori + indigo gradient and tie/knot patterns + cotton-linen fabric texture (indigo dye, not batik, not cyanotype); Theme: Frieren female character indigo-dyed fabric portrait—one person per image, vertical; Character likeness must be highly consistent with their original anime appearance; key hairstyle/hair color/facial features and aura/iconic traits clearly recognizable; avoid swapping into an unrecognizable passerby face. Female character details: Korean goddess vibe retained in indigo; large clear eyes with reserved white highlights. Characters (all from Frieren: Beyond Journey's End, one character per image, clearly adult, East Asian aesthetics): 1) Frieren (silver hair green eyes—green hinted with light indigo in indigo dye) 2) Fern (silver-blue hair) 3) Übel (purple-series long hair) 4) Serie (silver-white long hair, dignified) Clothing: cool travel outfit in indigo dye, not erotic. Composition: half-body, tie/knot pattern background, frayed fabric edges. Constraints: Frieren only; strong shibori indigo dye; recognizable; no national flags/rising sun; no large readable text.
