Design Ready To Drink Coffee Ads

Create a premium ready-to-drink coffee advertisement poster in a vertical 3:4 format for a fictional brand called {{BRAND_NAME: ROAST & RIVER}}. The campaign promotes {{PRODUCT: a canned oat cold brew coffee}} with the flavor name {{FLAVOR_NAME: Oat Cold Brew}}.

The scene features {{MODEL_DESCRIPTION: an adult male model in his late 20s with relaxed refined casual styling}} inside {{LOCATION: a minimal urban café with warm walnut counters, pale plaster walls, and soft morning window light}}. The mood should feel focused, calm, modern, and editorial, not rustic or overly cozy.

The model is posed {{MODEL_POSE: seated casually at the counter, one hand near the product, looking slightly down as if beginning the day}}. He wears {{WARDROBE: a cream overshirt, white tee, dark trousers, and clean minimal sneakers}}. The lifestyle element should feel natural and premium without overpowering the can.

The hero product is a large realistic can in the foreground, sharply focused, slightly oversized by perspective, with accurate aluminum curvature and controlled reflections. The can has {{PACKAGING_DETAILS: a matte espresso-brown finish, cream typography, subtle condensation, clean pull tab, and premium label spacing}}. The label reads {{BRAND_NAME: ROAST & RIVER}} and {{FLAVOR_NAME: Oat Cold Brew}}.

At the top center, add bold editorial typography reading {{HEADLINE: MORNING, MADE SMOOTHER}}. Beneath it, place the tagline {{TAGLINE: Slow brewed. Ready now.}}. Along the lower third, include four icon badges reading {{BADGE_1: LOW ACIDITY}}, {{BADGE_2: OAT BLEND}}, {{BADGE_3: COLD BREWED}}, and {{BADGE_4: NO ARTIFICIAL FLAVORS}}.

At the bottom right, show three smaller can variants arranged neatly: {{VARIANT_1: Classic Black}}, {{VARIANT_2: Vanilla Oat}}, and {{VARIANT_3: Mocha Draft}}.

Use soft morning daylight, warm fill, realistic reflections on the walnut counter, shallow background depth of field, tactile wood grain, crisp product focus, and a premium café campaign aesthetic.

Avoid real coffee brand references, messy latte art, excessive steam, spilled coffee chaos, cluttered café shelves, unreadable can text, distorted cans, random hands, fake rustic props, and over-saturated food styling.
