Celebratory Four-Woman Fashion Portrait

Create a bright celebratory horizontal group portrait on a clean white background, featuring exactly four smiling young Japanese women arranged shoulder-to-shoulder in a mixed photorealistic and fashion-illustration style. The first woman on the far left is fully colored and semi-realistic, wearing an orange floral ruffled dress, hair in a loose elegant updo with wispy strands, gold hoop earrings, and giving a thumbs-up toward the viewer. The second woman near center-left is the main focal figure, fully colored with long voluminous wavy chestnut-brown hair, warm glowing skin, gold drop earrings, a delicate necklace, and a translucent ivory blouse, smiling directly at the viewer. The third woman near center-right is fully colored, slightly in front, with a short dark-brown bob haircut, gold hoop earrings, a sleeveless white top, and a shiny gold scarf tied at the neck, holding the scarf with one hand while smiling brightly. The fourth woman on the far right is intentionally unfinished as clean sepia-and-gold line art with minimal pale yellow washes, short wavy light hair, earrings, necklace, and a cheerful smile, as if she is being drawn into the scene. Add floating gold confetti pieces and soft orange ribbon streamers behind them, creating an anniversary celebration mood. Use crisp facial features, glossy eyes, natural makeup, warm highlights, elegant Japanese magazine beauty aesthetics, watercolor-like rendering, delicate ink outlines, and a festive yet airy composition. Keep the background pure white, no text, no logo, no watermark. Use a 16:9 landscape canvas.
