[Subject] Side-by-side comparison image with two vertical portrait panels of the same tattooed young woman interpreted in two different model styles. Left panel: realistic version, early 20s, feminine presentation, light olive skin, long straight black hair in a high ponytail with small orange flowers placed through the hair, thin round metal glasses, small septum ring, large yellow drop earrings, layered silver necklaces, black tank top, floral chest and shoulder tattoos, and puckered kiss-face lips. Right panel: stylized or beautified version of the same woman, still wearing thin round glasses, yellow earrings, layered necklaces, and visible tattoos, but with turquoise-blue hair styled into two high buns with long front sections falling down. She has a softer smile, smoother face, slightly more illustrative or beautified finish, gray sleeveless top, and the same general identity translated into a more stylized rendering. Bottom labels identify the left as "NANO-BANANA PRO" and the right as "NANO-BANANA".
[Environment] Minimal studio-style portrait background with soft beige or warm neutral backdrop, no environmental props. This image is a direct comparison poster illustrating the difference between a more realistic output and a more stylized output while preserving the same character identity markers.
[Composition/Camera] Vertical 3:4 canvas divided into two equal rounded-corner columns with a narrow divider. Both portraits are chest-up, centered, front-facing, and tightly cropped. Subject fills most of each panel. The left panel emphasizes realism and sharper photographic fidelity. The right panel emphasizes a cleaner, more beautified, somewhat illustrative aesthetic. Composition must remain highly symmetrical and consistent so viewers can compare style drift, identity retention, and detail fidelity.
[Lighting] Soft frontal portrait lighting with balanced illumination on both faces, gentle catchlights in the eyes, subtle reflections on glasses, and minimal shadow. Light should be neutral and flattering, allowing differences in texture realism and rendering style to show naturally. Skin and tattoos must remain readable in both panels.
[Style/Rendering] Comparison poster for AI portrait generation quality. Left panel should feel photorealistic, detailed, and grounded. Right panel should feel smoother, more stylized, and slightly digital or illustrated while retaining realism-adjacent portrait structure. Both images should remain polished and attractive, but the contrast between realism and stylization should be obvious. No extra poster graphics beyond the bottom labels.
[Detail constraints] Keep exactly two portrait panels, preserve key identity markers across both sides: glasses, yellow earrings, layered necklaces, tattoos, youthful female face, and centered framing. Maintain bottom labels "NANO-BANANA PRO" on the left and "NANO-BANANA" on the right. Do not add side props, cluttered backgrounds, extra people, or text beyond the labels. The comparison is about fidelity versus stylization, not about different scenes.
Negative prompt: single panel only, missing tattoos, missing glasses, no yellow earrings, no labels, cluttered background, wildly different identities between panels, cartoon exaggeration, anime eyes, painterly texture, distorted face, low-detail jewelry, no septum ring, extra objects, watermark.
Suggested parameters: aspect ratio 3:4, 70-85mm portrait feel, shallow depth of field, 28-36 steps, CFG/style strength 6.5-8, sampler DPM++ 2M Karras or equivalent, seed around 465328.
Delta prompt strategy:
1. If the split-screen disappears: add "two equal vertical comparison panels with a narrow divider and matched crop".
2. If identity diverges too much: add "same woman, same facial structure, same jewelry, same tattoos across both panels".
3. If the left panel is not realistic enough: add "left panel photorealistic, crisp skin detail, natural hair texture, grounded realism".
4. If the right panel is not stylized enough: add "right panel smoother, more beautified, slightly illustrative finish with turquoise twin buns".
5. If the tattoos fade: add "clear floral tattoos across chest, neck, and shoulders visible in both panels".
6. If the earrings disappear: add "large yellow drop earrings clearly visible on both sides".
7. If the orange flowers on the left vanish: add "small orange flowers tucked into the black ponytail on the left panel".
8. If the labels disappear: add "bottom left label NANO-BANANA PRO and bottom right label NANO-BANANA in bold white text".
9. If the background gets busy: add "plain warm neutral portrait backdrop with no props or decor".
10. If the glasses distort: add "thin round metal eyeglasses with natural reflections and correct lens proportions".
