Japanese-style cool summer semi-realistic illustration, subject is [xxx], 9:16, low angle shot looking up, subject occupies the center of the frame. Deep high-saturation cobalt blue sky, a small amount of thick white clouds, strong blue-white contrast. Sunny day hard light from the top side, cold white highlights, blue-gray shadows, skin and clothing with blue ambient reflections. Impasto combined with fine line art, delicate and visible brushstrokes, facial features are cold and transparent, hair strands slightly floating, clothing is loose and pure white, with folds and cold blue reflections. Overall cool, quiet, lonely, free, summer transparency, like high-end Japanese literary illustrations and poetry covers. No text, no watermark, no logo, no photography feel, no 3D.
