Cena fotorrealista de um estudioso de caligrafia

A realistic indoor portrait of {argument name="subject" default="Elon Musk"} standing at a traditional Chinese writing desk, practicing brush calligraphy on a large sheet of rice paper. He wears a black Tang-style Chinese jacket with frog-button closures and subtle embroidered texture, leaning slightly forward with one hand resting on the table and the other holding a calligraphy brush vertically over the paper. The scene is a warm, elegant scholar's studio with dark wooden furniture, a carved brush stand holding exactly 4 hanging calligraphy brushes on the left, an ink stone and small ink containers in the lower-left foreground, and a small ceramic vase on a side table in the back. Behind him are exactly 2 vertical hanging scrolls: the left scroll prominently displays the large characters {argument name="left scroll text" default="Full River Red"}, and the right scroll contains a longer column of Chinese calligraphy. A wooden lattice window appears on the right side, letting in soft ambient light. The paper on the desk is filled with many lines of black Chinese calligraphy in flowing semi-cursive script, suggesting he is writing {argument name="written poem" default="《Full River Red》"}. Use a documentary-style, photorealistic aesthetic with cinematic warm lighting, rich wood tones, authentic calligraphy tools, shallow depth of field, waist-up composition, and a serious, focused atmosphere.
