A vibrant, ultra-realistic outdoor photograph capturing a full-body portrait of a young man (same face as reference image, 100% accuracy) seated joyfully on a rustic wooden swing over clear water. He wears a black baseball cap, a black and white plaid long-sleeved shirt unbuttoned over a white t-shirt, white shorts, and black sandals. His left foot is playfully splashing in the crystal-clear, vibrant teal water, creating dynamic ripples, while his right foot rests on the swing. He is smiling warmly, looking directly at the viewer with a happy and relaxed expression. Beneath him and around his feet, numerous colorful Koi fish in striking shades of orange, white, black, and yellow swim gracefully. The background features lush, out-of-focus green pine trees, illuminated by a warm, golden sunlight filtering from the upper left, creating a soft lens flare and an ethereal glow. The overall mood is serene, joyful, and inviting, with a dominant color palette of vivid teals, emerald greens, and the striking oranges and whites of the fish, all highlighted by the warm golden hour light.
