Replace “bright pink soda can inside a white lifebuoy” with “large bright pink soda can as the dominant central subject, partially covering the lifebuoy,” and change “sharp focus on the can and lifebuoy” to “tack-sharp focus on the soda can, with the lifebuoy slightly softened.” Keep “clean overhead composition” so the can remains easy to read.

Replace “soft late-afternoon sunlight coming from one side” with “bright direct midday sunlight with sparkling specular highlights,” and change “gentle ripples” to “lively radiating splashes and energetic water ripples.” Retain “vibrant summer color palette,” but add “bold saturated cyan and coral accents” if you want stronger contrast around the pink can.

Replace “bright pink soda can” with a specific substitute such as “turquoise sunscreen bottle with a white cap,” and replace “glossy soda-can surface with clean highlight streaks” with “smooth glossy sunscreen-bottle surface with clean vertical highlight streaks.” For a consistent series, keep “inside a white lifebuoy with blue bands,” “clear deep teal swimming pool water,” and “clean overhead composition” unchanged.
