Replace “sharks swimming around him” with “four large sharks occupying most of the frame, their dorsal fins and bodies clearly visible around and beneath him,” and change “sharks circling close to the man” to “tight, aggressive circle with the nearest shark passing within arm’s reach.” Keep “top-down overhead framing” so their arrangement remains legible.

Replace “golden-hour warm sunlight” with “low, storm-filtered late-evening light,” and change “tense surreal adventurous mood” to “foreboding, claustrophobic survival mood.” Reduce the cheerful contrast in “natural colors” by adding “desaturated teal water, muted beige skin tones, and deep black shadows,” while retaining “high-contrast rippling caustic highlights” for uneasy surface distortion.

Keep “shirtless man standing in shallow, crystal-clear sea water,” “sharks circling close to the man,” and “top-down overhead framing” fixed, then vary one load-bearing phrase per image: replace “golden-hour warm sunlight” with “overcast dawn,” “moonlit night,” or “harsh midday sun,” and swap “deeper teal-blue palette” for “emerald green,” “steel blue,” or “murky gray-green.” This preserves the subject and composition while producing clearly different lighting and color studies.
