Cool Japanese Summer Illustration

A semi-realistic Japanese-style cool summer illustration, with [xxx] as the main subject, 9:16, low camera angle, and the main body occupying the center of the frame. A deep, highly saturated cobalt blue sky, with a few heavy white clouds and a strong blue-white contrast. On sunny days, hard light shines from the side and above, with cool white highlights, blue-gray shadows, and skin and clothing reflecting blue ambient light. Thick application combined with fine line art, with delicate and visible brushstrokes, cool and clear features, slightly flowing hair, loose and pure white clothing, with wrinkles and cool blue reflections. Overall, it is cool, quiet, lonely, free, with a summer transparency, like high-end Japanese literary illustrations and poetry covers. No text, watermark, logo, no photography feel, no 3D.
