ภาพการ์ตูนสไตล์แบนสุดแปลกตา

Vertical bizarre flat cartoon poster portrait of [the boy from the reference photo] with a tall geometric head shape, a long narrow neck, huge round eyes, a tiny mouth, and an unflappable grin. He is wearing [clothes from the reference photo], with a [puppy] perched on his head like a living hat. Style features pure black outlines, smooth flat color fills, simplified facial geometry, playful surreal character design, and a bold graphic palette dominated by [blue]. Background: [coffee shop interior decor] rendered in simplified flat geometric shapes, clear depth, and clean cartoon perspective. 2D digital illustration poster, strictly flat graphics, no realism, no 3D rendering, no painterly shading.
