GPT Image 2 Reference Tutorial Banner

Prompt

Goal: Create a clean Japanese promotional thumbnail/banner for a GPT Image 2 tutorial about using reference images to keep the same person consistent. Canvas: 16:9 horizontal banner, 1200×675 style, soft pale blue and white background with large organic blob shapes. Use a polished educational course-thumbnail aesthetic, airy spacing, high readability, no harsh shadows. Layout: Split composition with a realistic portrait on the left occupying about 40% of the canvas, and a text-heavy information panel on the right occupying about 60%. The right side has a large white rounded organic shape as the main text area. Add small decorative dotted grids in the top-right and bottom-left corners, a light diagonal hatch pattern near the lower-right edge, and coral accent marks beside the headline. Subject details: On the left, show one smiling Japanese woman in her late 20s to early 30s, photographed from the waist/chest up, facing the camera. She has shoulder-length softly layered black hair, natural makeup, warm friendly expression, and wears a peach sheer button-up shirt over a white ribbed camisole with a delicate gold necklace. Background behind her is bright, soft-focus, and slightly green-white like daylight through a window. Text content: Include exactly 4 text blocks on the right: 1) a dark navy rounded pill at the top reading 「GPT Image 2 実践編 ③」; 2) a large navy Japanese headline reading 「基準画像を\n作った、その次は？」 with a coral underline under the final phrase; 3) a thin outlined rectangle subtitle reading 「人物固定の具体的な使い方」 with 「具体的な」 highlighted in coral; 4) a bottom checklist row with a pale blue circular check icon followed by 「毎回どの基準画像を使う？」. Keep all Japanese text crisp, centered within its area, and use elegant Mincho-style serif for the main headline with modern sans-serif for smaller labels. Color palette: Deep navy text, pale powder blue background, white panels, peach/coral accents matching the woman's shirt, and light blue-gray icon details. Constraints: Use exactly one person, exactly four text blocks, exactly one check icon, and exactly three main decorative accent types: dotted grids, coral rays/underline, and diagonal hatching. Avoid extra logos, watermarks, English translations, or additional text.
