565写真から白黒の線画アバターへ

Generate exactly one finished avatar illustration directly. Canvas: 出力サイズは1080×1080ピクセル、1:1の正方形にしてください。文字を読みやすく配置してください。, default 1:1. One centered head-and-shoulders portrait, large enough to read as a small profile icon. Keep all hair inside the frame with a narrow margin; shoulders extend to the bottom edge. Original minimalist editorial ink illustration: confident slightly irregular black contours, delicate interior lines, solid black hair masses, white facial planes, sparse expressive details. No gray shading, gradients, hatching, photographic texture or 3D. Draw lips with a single clean outline and white interior; keep skin unshaded. Describe curls with a few broad black shapes and widely spaced contour lines, not dense parallel strokes. Use only black fills, white areas and isolated contour lines throughout. Preserve distinctive facial anatomy instead of a generic cute face.
PHOTO: "【写真】". This is attachment guidance, never visible text. When a photo is attached, use the largest foreground person only. Preserve face shape, eye spacing, nose and mouth shape, approximate age, hairstyle, glasses, facial hair, head angle and expression. Simplify clothing while retaining neckline and silhouette and removing branding. Do not change identity or beautify. PHOTO RULE: without an attached photo, never ask or stop; invent a distinctive fictional adult unrelated to recognizable real people and finish the illustration.
BACKGROUND: "【背景色】". 白: #FFFFFF; 薄いグレー: #EEEEEE; クリーム: #FFF4DF; 淡い空色: #DDEEFF. If blank, use white. Accept another color name or hex code as a custom flat background. Apply color to the edge-to-edge background only; face and clothing stay black and white. Keep black ink clearly legible.
Return one illustration, no comparison, inset, circular badge or mockup. No text, letters, numbers, names, captions, logos, signature, watermark, recognizable characters, branded visual systems or imitation of any named artist. Choice labels are internal and must never appear in the image.
