    Photorealistic fashion portrait of the adult woman in the uploaded reference image (DO NOT TOUCH FACE). Create a glossy wet-look fashion portrait of the woman with slicked-back hair and a few face-framing wet strands. Her body is angled at chest level, photographed from a slightly elevated perspective, and she looks away from the camera with a relaxed dreamy expression. Makeup is polished and luminous, with defined eyes, dewy highlights, glossy lips, natural skin texture, and a clean fashion-editorial silhouette. The setting is a humid pool, spa, or balcony environment with glossy surfaces, cyan-blue neon reflections, and a single magenta accent in the background. Skin and hair look lightly misted, not plastic. She wears a black glossy one-piece swimsuit with thin straps, layered silver necklaces, wet slicked hair, and shoulders lit by cyan pool reflections. The mood is nightlife fashion, clean and non-explicit. Shot with an editorial portrait lens, tight composition, shallow depth of field, and clean subject separation. Photorealistic, high-resolution fashion photography with natural skin texture, realistic pores, accurate hands, crisp fabric detail, clear eyes, subtle makeup texture, and no beauty-filter plastic smoothing. No text, watermark, logos, cartoon, anime, CGI, extra fingers, warped hands, broken wrists, distorted face, mannequin stiffness, or excessive empty space.

    Prompt

    Using the person in the uploaded reference image (DO NOT TOUCH FACE), recreate this scene: Subject: An adult woman in a close, upper-body shot, taking a selfie with about a 30% side-facing angle. Her head is slightly tilted, she looks straight into the camera, and she wears a subtly reserved smile—her emotion feels soft and approachable. Photography language: A handheld front-camera smartphone selfie shot from a higher angle looking down. A mild wide-angle perspective makes her face feel closer to the lens while the background falls away. The composition isn’t studio-perfect; it carries a touch of spontaneity and the humid, outdoorsy “breathing” feeling of the moment. Makeup & facial vibe: The eye makeup is more refined—noticeable eyeliner and curled lashes give the eyes a dewy, “watery” sparkle. The cheeks have a faint pink-toned blush with a soft-matte base; overall it’s clean and sheer, but clearly well-groomed and thoughtfully done. Hair: Long, straight deep-brown hair with a side part (leaning slightly toward a middle part). A few loose strands fall along the sides of her face, adding a casual, naturally imperfect realism. Outfit: A blue-and-white gingham bikini top. The brown piping/trim and the halter/strap structure are very clear, making it a strong visual signature. Some chest skin is visible. Accessories: A thin silver chain necklace with a small, shiny clover/flower-shaped pendant. Setting: Outdoors in a wooded area or dense shrubs, with greenery filling most of the background. The ground shows dirt and fallen leaves, and there’s a small patch of water or wet ground in the lower-left corner—suggesting a creekside or a small forest pool nearby. Lighting: Dappled sunlight filtering through leaves, creating both highlights and soft shadows. This kind of “physical” natural light makes the skin look more dimensional and keeps the shot feeling like a real, casual phone photo.

    A scene featuring the woman in the uploaded reference image (DO NOT TOUCH FACE). A medium-sized vertical photograph depicting a woman positioned slightly right of center in a room with smooth, pale gray marble tiles in the background. The marble surface continues to act as a polished countertop on the right side, approximately 15-20 cm thick. The subject is photographed from mid-thigh upwards, leaning slightly back, with her left hand resting on the countertop and her right hand raised holding a clear champagne glass filled with a pale gold liquid. The eyeshadow is in soft pastel shades (peach, beige, light pink) with a smooth transition to a darker tone at the outer corner of the eye. Black eyeliner with a slight wing accentuates the shape of the eyes. The eyelashes are long, voluminous, and thickly coated with black mascara. The lips are coated with a soft pink gloss with a subtle shimmer. A subtle highlighter is applied to the cheekbones, bridge of the nose, and above the upper lip for a healthy glow. Skin appears perfectly even, with a light, dewy finish that mimics a natural glow. The woman has a striking hairstyle: voluminous waves framing the face, with a few strands casually falling onto the cheeks and neck, creating a sense of effortless elegance and luxury. She wears a short ivory satin dress with a high round neckline and long, translucent, wide lace sleeves with delicate floral patterns. She wears large gold sphere earrings. The lighting is harsh from the camera flash. The composition is clean, with a moderate depth of field, preserving the clarity of the dress and pose. Shot with a 50mm portrait lens.

Key takeaways

Pick the model based on what you care about most: taste, completion rate, or a tighter safety filter.

Best-looking: Nano Banana 2

NB2 won the eye test most often. It accepted 14/17 prompts and was best at keeping the final image natural, not over-polished.

Least blocked: Seedream 4.5

Seedream was the easiest to get through. It accepted 17/17 prompts and was the strongest at keeping the face consistent.

Strictest: GPT Image 2 Medium

GPT blocked 12/17 prompts. Use it when you want the most conservative lane; when it does accept, the output can still be excellent.

Bottom line

NB2 for the best images. Seedream when you need the prompt to actually run. GPT when strict filtering matters more than completion rate.
