Premium Fast-Food Melt Campaign Poster

Create a bold 9:16 vertical fast-food campaign poster for {{BRAND_NAME}}, preserving a split-world visual structure.

The upper half is a premium social-post-inspired fast-food environment featuring a hyper-realistic burger combo. The lower half is a clean warm cream background containing one minimal cartoon reaction character. Connect both worlds through one dramatic central stream of molten cheese that acts as the primary visual axis of the entire composition.

UPPER SECTION:
Create a premium social-post-style fast-food scene with one gigantic double-patty cheeseburger centered prominently. Shoot the burger front-facing from a slightly low eye level for maximum appetite impact.

Make the burger extremely realistic and indulgent:
- glossy sesame bun
- two thick juicy beef patties
- molten cheddar overflowing between the layers
- rich glossy sauce
- fresh pickles
- subtle grilled meat texture
- realistic crumbs, moisture, grease, and edible surface detail

Push the visual energy toward a bold, viral, high-impact commercial aesthetic while maintaining a polished premium finish.

Make the molten cheese more forceful and vertically dominant, as if the burger is erupting with molten energy.

Place a branded red soda cup with straw and a small fries carton nearby, but keep both clearly secondary to the burger.

Use a warm red fast-food interior in the background with simplified glowing menu-board light blocks, subtle branded packaging atmosphere, and controlled environmental depth. Keep the background premium, clean, and internationally campaign-ready rather than busy or cluttered.

CHEESE BRIDGE:
The molten cheese is the central hero motion.

The cheese must begin naturally from the burger core and descend in one long, luxurious, glossy stream along the exact central axis of the composition.

Make the stream:
- hot
- thick
- elastic
- gravity-driven
- physically believable
- glossy with refined highlight rolloff
- naturally narrowing and widening
- visibly viscous
- rich orange-yellow cheddar color

The cheese stream should feel like a powerful visual impact column connecting the upper photographic world to the lower illustrated world.

LOWER SECTION:
Place one simple black-and-red cartoon-style youth character lying on a clean cream or pale warm-beige field.

The character lies horizontally on the ground with the mouth open upward, directly receiving the central cheese stream.

Keep the illustration:
- minimal
- iconic
- playful
- flat and graphic
- black linework with restrained red accents

Add only a few tiny splash or motion accents around the character.

The character is the comic emotional payoff and must not compete visually with the burger or central cheese stream.

BRANDING AND INTERFACE:
Create an original fictional brand identity using {{BRAND_NAME}}.

The upper section may include a premium social-post-inspired header, simple interface cues, tiny original icons, subtle post details, and restrained UI elements.

All interface elements must be newly invented and generic. Do not copy any real social media platform, interface, logo, icon system, or recognizable text.

Keep typography and UI secondary to the burger and cheese.

Push the overall direction toward a polished flagship fast-food campaign: clean hierarchy, sophisticated spacing, believable branded details, and premium commercial art direction.

LIGHTING AND REALISM:
Use warm cinematic restaurant lighting in the upper section.

Create soft glow from menu-board lights and strong appetizing highlights across:
- sesame bun
- beef patties
- molten cheese
- fries
- soda cup

The burger must feel hyper-real and premium, with refined meat, bun, sauce, pickle, and melting-cheese textures.

The lower illustration remains intentionally flat and graphic, creating a strong high-low visual contrast.

Keep shadows controlled, clean, soft, and commercially polished.

COLOR SYSTEM:
Use a bold campaign palette:
- dominant fast-food red
- molten cheese orange-yellow
- warm burger browns
- cream lower background
- black cartoon linework
- small white UI accents

Keep the palette saturated, high-contrast, cohesive, and internationally campaign-ready.

COMPOSITION:
Maintain the split-world structure clearly.
Keep the burger as the dominant upper focal point.
Keep the molten cheese perfectly aligned with the central vertical axis.
Make the cheese visually connect the two worlds.
Keep the lower character centered beneath the cheese.
Preserve generous negative space in the lower cream field.
Create a strong visual hierarchy that reads immediately at thumbnail size.

The final image should feel like a premium, viral-ready fast-food campaign poster where realistic food photography, physical food motion, social-media energy, and playful graphic storytelling merge into one coherent advertisement.
