A medium shot, eye-level anime illustration featuring two girls standing back-to-back in the center of a vertical composition. On the left, a modern-style idol is depicted with a color scheme of light blue, black, and green, wearing a contemporary trendy idol outfit with sharp lines and stylish accessories, her hands resting casually in her pockets. On the right, a Showa-era style idol is presented in a color palette of pink, white, and orange, dressed in a vintage-inspired frilly dress with a large bow and a classic hairstyle, her hands clasped gently in front of her. The background is a minimal, pop-art style space with few colors and simple geometric shapes, devoid of complex detail. The visual style is a flat pop aesthetic with minimal shading and clean outlines, using a bright, saturated color palette and a cheerful, nostalgic yet modern atmosphere.
