Mixed-Media Streetwear Poster

High-resolution mixed-media studio portrait combining photography with flat white hand-drawn vector doodles and collage overlays. Full-body shot of a {argument name="subject" default="confident young man"} on a {argument name="background color" default="vivid solid blue background"}, dressed head to toe in a monochromatic blue {argument name="brand" default="Adidas"} streetwear fit with crisp white details.

Subject: young man, light goatee, neutral confident expression, head tilted slightly left, body angled slightly right, right hand raised near his face, left leg crossed in front of the right. Low-angle full shot framed head to toe, 35mm-equivalent lens, deep depth of field, even soft front-right studio lighting in neutral white, gentle self-shadows on the left side of face and neck.

Outfit:
- Royal-blue denim/canvas bucket hat (#003399), brim pulled slightly down, visible white contrast stitching around brim and crown.
- Open vivid-blue sherpa fleece jacket (#0044CC), nubby high-pile texture, silver snap on the collar, sleeves slightly pushed up.
- Royal-blue cotton T-shirt underneath with a large white Adidas Trefoil outline printed across the chest.
- Dark-wash indigo relaxed-fit jeans (#2A3B55) with heavy white contrast stitching along seams and pockets, cuffs rolled up showing the lighter inside of the denim.
- Pristine all-white Adidas Superstar sneakers (smooth leather upper, rubber shell toe, three white-on-white stripes); right foot planted, left foot up on the toe.

Flat white hand-drawn vector overlays (sharp edges, doodle aesthetic, no shading):
- Three thick vertical white lines dropping from his raised hand down to a hand-drawn dynamic vocal microphone (mic-drop motif).
- An isometric outlined boombox to his center-right showing speaker mesh, handle, buttons, cassette deck.
- A large flat white Adidas Trefoil logo in the bottom-right corner.
- Short radiating motion/sound stroke lines around his head and the boombox.
- Jagged shattered-glass crack lines fanning out across the floor under his feet.

Behind him: amorphous flat liquid-blob shapes in a slightly more saturated blue (#5CAFF0) wrapping around the subject as a secondary background layer over the solid blue base.

Composition: subject centered, asymmetrical balance from the doodles filling the negative space, high-contrast and dynamic. Color palette strictly vivid blue, deep blue, and pure white. Sharp boundary between the photoreal subject and the flat 2D vector overlays so they read as layered, not blended. Vibe: energetic, urban, artistic, cool, album-cover energy.
