Flux AI: couple travel

Create an image showing Mark (a man in his early 30s with short brown hair, light stubble, and medium skin tone, wearing a white button-up shirt with the sleeves rolled up and blue jeans) and Sarah (a woman in her late 20s with shoulder-length blonde hair, fair skin, and soft blue eyes, wearing a light white shirt and a brown skirt) walking along the shoreline. The focus should be on their faces, smiling and enjoying each other's company, with the waves in soft focus behind them.
