Vertical, sunlit portrait of a joyful young couple

Vertical, sunlit portrait of a joyful young couple sitting on a grassy mountain ridge overlooking a turquoise alpine lake and a small village in the valley below, woman seated behind man with both forming heart shapes with their hands—her arms raised above his head creating a larger heart, his hands in front creating a smaller heart—natural candid smiles, warm connection, relaxed romantic vibe. Soft pastel clothing: she in a light pink flowy dress or robe, he in a light grey long-sleeve tee, dark wavy hair and full beard, subtle bracelets and a ring. Lush green slopes, wildflowers near the foreground, dramatic layered mountains and winding shoreline in the background. Golden natural light, gentle rim light on hair, crisp skin detail, vibrant but natural colors, slight background blur for depth (shallow depth of field), high-resolution, cinematic, intimate travel photography composition, 9:16 vertical frame, eye-level perspective, authentic, joyful, serene atmosphere. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
