Video prompt: Dynamic 4K UHD video, 8s, 60fps, loopable, medium shot, vertical composition, cool Japanese teenage boy in black hoodie with traditional wave pattern, ripped jeans, white sneakers, red bandana on wrist. Standing in vibrant Tokyo Harajuku: colorful street art, fashion boutiques with bold signs, trendy passersby, cherry blossom trees lining street. Dynamic actions: He slowly adjusts his hoodie with both hands, pulling the hood up slightly then letting it fall back; he picks up his skateboard from the ground with one hand, spins it once on his finger, then places it back under his feet; he leans against a wall, crossing his arms, then uncrosses them to adjust the red bandana on his wrist; he nods his head to an invisible beat, his foot tapping on the ground; a group of friends walks by, and he waves at them with a cool smile, not moving from his spot. Lighting: Bright afternoon sunlight, vibrant colors, high contrast, sharp details on hoodie wave pattern and skateboard, no text, no watermark. Style: Trendy, youthful, dynamic aesthetic. --ar 9:16 (Vertical, 1080x1920, YouTube Shorts Standard)
