Use the provided product image as the exact hero product and create a beautiful desktop e-commerce product detail page mockup in a 16:9 ratio. Keep the product’s real shape, proportions, materials, colors, and branding consistent with the input image. Design a premium, modern, minimal product showcase webpage with strong commercial appeal, suitable for product presentation, retail concept design, brand landing pages, and UI mockups. Layout should include: a clean top navigation bar, left-side thumbnail gallery or supporting product visuals, a large central hero product display with soft studio lighting and realistic shadow, and a right-side product information panel with product title, price, concise marketing copy, selectable options, quantity control, and strong call-to-action buttons. Add a lower information area with feature icons, technical specifications, material highlights, and short selling points arranged in a polished grid. Use elegant sans-serif typography, precise spacing, thin divider lines, subtle cards, white or very light neutral background, and a calm premium color system derived from the product itself. Overall look: realistic, high-end, conversion-focused, clean desktop UI, refined industrial design presentation, dribbble/brand-site quality, not mobile, not cluttered, not cartoon.

A beautiful and attractive European white young woman taking a selfie in the gym, wearing yoga clothes and showing off her curvaceous figure.

Edit the image while keeping the original photo completely unchanged — including the person, face, body, pose, lighting, and gym background. Add multiple small, cute chibi-style “mini versions” of her around the image. Each mini character should have a big head, expressive facial features, and match her hairstyle and outfit. Depict each mini version doing different gym-related activities: one cheering with arms raised one running in running shoes one drinking from a shaker bottle one wearing sporty running glasses one climbing near her leg Enhance the image with playful, hand-drawn doodles and handwritten notes in white and pink ink, in a scrapbook style. Include elements like arrows, stars, hearts, sparkles, and sketchy lines. Add cute, handwritten gym-themed motivational phrases: “lift strong” “stronger every rep” “no pain no gain” “sweat now, shine later” “progress over perfection” “train hard, stay soft” The overall vibe should feel fun, energetic, and feminine.
