“Cinematic, photorealistic artwork of a sorrowful young woman in a flowing ivory lace dress kneels in shallow surf at the waterline during sunset. Her long, windblown dark hair frames her downcast face; a tear flows down her cheek and into the water, one hand presses against her chest, glowing faintly crimson to suggest her still-beating heart, while her other fingertips touch the water. The world behind her remains beautiful: a golden sun shines over restless waves, seabirds cross the sky, and fiery peach clouds fade into star-filled indigo. In the wet sand, her reflection becomes a dark cosmic void. Stars ripple around a fading, ghostlike image of her partner deserting her and dissolving into darkness. The tear forms concentric ripples, disturbing an entire universe. Contrast warm golden life above with cool blue-black devastation below. Natural cinematic lighting, detailed water reflections, realistic anatomy, restrained grief. No text, borders, or collage.”Concept art & fantasy
