一個穿著寶藍色的小男孩的明亮肖像

"A bright, casual selfie-style portrait of a young man with thick, wavy dark brown hair and a full, neatly groomed black beard and mustache, smiling broadly with teeth showing and a warm, friendly expression. He faces the camera with his shoulders slightly angled. He wears a royal blue sleeveless cut-off t-shirt with a black-and-white tiger face graphic printed on the chest, and a small stud earring is visible. The setting is a simple indoor bedroom with a white ceiling, a wall-mounted air conditioner on the left, a white wardrobe with grey sliding doors, a green panel leaning against the wall, and a few clothes, bags, and small items sitting on top of the wardrobe. Soft, even natural daylight, clean and slightly overexposed look, natural skin tones, candid social-media style, shot on a smartphone front camera, vertical 3:4 aspect ratio, sharp focus on the face."

**Tips:**
- Add *"photorealistic, natural skin texture, soft window light"* for a more lifelike result.
- For a cleaner look, replace the cluttered wardrobe top with *"a tidy minimalist bedroom background."*
- To emphasize the shirt, add *"bold tiger graphic print, vivid royal blue fabric."*
