Prompt:

High-quality semi-realistic Japanese-style half-length illustration: the protagonist is a young male with short black hair, slightly tousled and flowing in the breeze. He wears a dark-colored blazer over a light blue shirt, with the collar casually open, and detailed folds and light-shadow playing on the fabric. His face is portrayed from a front-left angle, with a calm and confident expression. The background is simple, primarily featuring a clear sky and distant city skyline, with cool tones and soft highlights in the upper left corner. Please recreate this in high resolution, maintaining the basic composition's outlines while enhancing the hair layers, clothing texture, and background lighting effects, overall presenting a sharp, mysterious aura.
