Image-to-image identity transformation using the provided master reference image as the immutable source. Preserve the original scene with absolute fidelity while maintaining a strict 3:4 vertical aspect ratio. Retain the exact sophisticated indoor editorial setting featuring a dark, textured wall backdrop with subtle painterly character, deep tonal richness, and understated luxury. Preserve the intimate environmental storytelling of quiet confidence, introspection, and refined masculinity. Maintain the same high-fashion visual philosophy and premium portrait aesthetic without introducing reinterpretation or additional elements. Lock the original 3:4 composition, framing, and camera perspective exactly as shown in the master reference. Preserve the medium portrait crop featuring the seated subject occupying the right portion of the frame, while maintaining the generous negative space and textured wall presence to the left. Retain the precise subject scale, furniture placement, body orientation, and spatial relationships between the subject, armchair, and surrounding environment. Maintain the complete Technical DNA without modification: cinematic editorial portrait realism, shallow depth of field with subtle environmental separation, natural lens compression characteristic of premium portrait photography, crisp focus concentrated on the face and upper body, and an elegant magazine-quality finish. Preserve the original soft directional lighting entering from the side, maintaining identical highlight placement across the face and hair, gentle shadow transitions, skin rendering characteristics, contrast ratios, muted color grading, and sophisticated tonal depth. Retain the same refined luxury portrait treatment throughout. Preserve the complete Behavioral DNA exactly as captured: seated posture within the armchair, torso subtly angled, shoulders relaxed yet composed, one arm bent upward with the hand resting naturally near the opposite shoulder and collar region, fingers maintaining the same relaxed positioning, the other arm extending downward with the hand resting casually across the leg. Preserve the exact neck alignment, head orientation, slight chin positioning, gaze directed thoughtfully away from the camera toward the side, and the same emotional energy of calm confidence, contemplation, and understated charisma. Preserve the complete Styling DNA without alteration: tailored charcoal-gray suit with identical cut, structure, fit, lapel styling, sleeve proportions, fabric texture, and sophisticated drape characteristics. Maintain the original monochromatic styling approach, including the dark inner garment beneath the blazer. Preserve all accessories exactly as shown, including the metallic rings on the fingers and the understated bracelet details on the wrist, maintaining their original placement, scale, material appearance, and styling purpose. Retain the original well-groomed facial stubble aesthetic and overall polished fashion direction. Use the uploaded portrait image solely as the facial identity reference. Replace only the original subject's facial identity while preserving maximum resemblance to the uploaded person. Adapt facial structure, facial proportions, eye shape, eyebrows, nose, lips, cheek contours, jawline, skin characteristics, age indicators, and gender-specific facial traits to accurately reflect the portrait reference. Preserve the original hairstyle silhouette, side parting, volume distribution, texture, and overall grooming style whenever possible while integrating the uploaded person's authentic hair characteristics. Ensure seamless integration with the existing lighting conditions so the transformed individual appears genuinely photographed during this exact editorial portrait session. Do not modify, reinterpret, enhance, reposition, crop, or redesign the environment, composition, framing, furniture placement, pose, body position, camera angle, lighting setup, wardrobe, accessories, emotional atmosphere, storytelling intent, realism level, or photographic treatment. The final result must feel indistinguishable from the original image except for the facial identity substitution, creating the impression that the uploaded person was always the true subject of this luxury editorial portrait. If any visible text exists within the reference image, replace it with professionally refined alternatives aligned with the original theme, improving wording and typography while ensuring all generated text appears inside quotation marks. If no visible text exists, do not introduce typography, slogans, branding, or additional graphic elements. Strict output specification: render in a locked 3:4 aspect ratio while preserving the original composition as faithfully as possible within the vertical canvas.
