A stylish boy with a playful smile wears a chunky olive-mustard knit sweater.

"A stylish close-up portrait of a young man with thick, voluminous dark curly hair styled in a textured fringe that falls over his forehead and partially covers one eye. He has a trimmed black beard and mustache, and a soft, playful smile with a slight head tilt toward the camera. His fists are raised and tucked under his chin in a cute, expressive pose. He wears a chunky olive-mustard knit sweater with textured ribbed cuffs and a woven pattern on the shoulders, and a black cord necklace with a black crystal pillar pendant. The background is a plain, smooth warm-grey wall with soft gradient shading and gentle shadows. Soft, diffused studio-style lighting, muted earthy tones, natural skin texture, fashion-editorial selfie style, shot on a smartphone, vertical 4:5 aspect ratio, sharp focus on the face."

**Tips:**
- Add *"photorealistic, soft key light, subtle film grain"* for a more polished look.
- For a moodier feel, add *"dramatic side lighting, deep shadows."*
- To emphasize the hair, add *"defined curls, glossy texture, individual strands visible."*
