Reframe this concept as: children's sports magazine cover, full-body studio shot of a cheerful young girl in a dynamic, energetic running/jumping pose, radiating fun and healthy activity. She is wearing the EXACT SAME outfit as the reference: a periwinkle-blue short-sleeve polo dress with a white collar, white waist band, a small "LET'S RUN" mascot graphic on the chest, two white horizontal stripes near the hem, white crew socks, and white-and-pink sneakers. Do not alter the clothing, hairstyle, or her appearance in any way.Bright, polished, high-key studio backdrop in gentle white with playful pastel geometric props (coral arch, blue blocks) to match the original color palette. Crisp polished professional illumination, vivid saturated colors, crisp focus, glossy commercial photography look.Magazine cover layout: powerful playful masthead at the top reading "KIDS SPORT" in a fun rounded sans-serif font, colorful cover headlines around her such as "Let's Run! Fun Active Style for Kids", "10 Energetic Outfits", "Move • Play • Smile", plus a small price/issue tag and barcode in the corner. Modern, lively, kid-friendly magazine-editorial visual design, eye-catching and cheerful.Aspect ratio 3:4, portrait image orientation, high resolution, photo-real.
