Replace all the [BRACKETED] variables with your own creative choices. You can generate endless variations by mixing and matching foods, textures, and moods.

Variation #1
A flat lay illustration in clean Scandinavian style featuring a glass of milk, piped meringue swirl, sugar cube stack, and a paper straw arranged across a pastel background in a minimalist floating layout. Each object is rendered in simplified, geometric shapes, spaced with airy intention. The illustration uses cutout-style forms with smooth vellum texture for a tactile yet refined feel. A pale sky blue, sugar white, rose blush, and soft silver color palette defines the mood — calm and contemporary. Ultra-diffused light with cloudlike ambient softness enhances the flat graphic balance. The overall mood is whimsical, delicate, and pure — suited for modern packaging, branding, or gentle editorial food moments.

Variation #2
A flat lay illustration in clean Scandinavian style featuring a bowl of yogurt with a swirl of honey, sliced peach, pomegranate seeds, and a gold stirring spoon arranged across a pastel background in a minimalist floating layout. Each object is rendered in simplified, geometric shapes, spaced with airy intention. The illustration uses velvety brush texture with fine grain speckling for a tactile yet refined feel. A blush peach, pomegranate red, milk white, and soft terracotta color palette defines the mood — calm and contemporary. Feathered light with subtle reflective edges enhances the flat graphic balance. The overall mood is warm, dreamy, and softly luxurious — suited for modern packaging, branding, or gentle editorial food moments.

Variation #3
A flat lay illustration in clean Scandinavian style featuring a cluster of blueberries, a halved croissant, stacked sugar cubes, and a ceramic spoon arranged across a pastel background in a minimalist floating layout. Each object is rendered in simplified, geometric shapes, spaced with airy intention. The illustration uses matte paper cutouts with embossed grain for a tactile yet refined feel. A lavender cream, dusty rose, oatmeal beige, and blueberry gray color palette defines the mood — calm and contemporary. Soft diffused lighting with no hard shadows enhances the flat graphic balance. The overall mood is gentle, slow, and indulgent — suited for modern packaging, branding, or gentle editorial food moments.

🧩 Variable Tips:
[FOOD OBJECTS] → Choose iconic or seasonal foods that are easily recognizable from above (e.g., toast, coffee mugs, grapes, cookies).
[TEXTURE STYLE] → Think “what would this illustration feel like?” Try styles like soft chalk pastel, watercolor washes, or grainy card stock.
[COLOR PALETTE] → Pick 3–5 soft, harmonious colors (e.g., dusty rose, mint, lavender).
[LIGHTING STYLE] → Use phrases like “even ambient glow” or “gentle top-down light” to keep things soft.
[ATMOSPHERE] → Pick a vibe: whimsical, elegant, nostalgic, serene, etc.

🚫 Common Mistakes to Avoid:
Don’t overcrowd your layout — this prompt relies on spaciousness.
Avoid overly bright or saturated palettes — aim for soft, balanced tones.
Keep food choices minimal and graphic, not overly realistic or hyper-detailed.
