Replace “sharp focus on bottle and citrus” with “sharp focus on grapefruit segments, with the bottle slightly secondary,” and change “arranged around the bottle” to “large grapefruit segments in the foreground, partially overlapping and framing the bottle.” Keep “centered” if you want the fruit to dominate symmetrically, or use “bottle offset to the right” for a more editorial composition.

Replace “deeper autumnal red-to-amber gradient background” with “cool desaturated blue-gray gradient background,” and change “warm, clean, premium, modern” to “clinical, cool, minimal, modern.” Replace “soft shadows” with “cool directional studio shadows” while keeping “realistic refraction and reflections” so the glass remains the main technical feature.

Keep the fixed structure, including “clean product still-life framing,” “centered,” “studio lighting,” and “balanced, uncluttered composition,” then replace “transparent amber glass serum bottle with a dropper cap” only when changing the package and replace “grapefruit segments” with ingredients such as “lemon slices,” “green tea leaves,” or “lavender sprigs.” Match each ingredient with a related background phrase, such as replacing “red-to-amber gradient” with “pale yellow-to-cream gradient” for lemon.
