Serene White Grassland Portrait

Create a photorealistic outdoor portrait based on the reference image. A young man with the same facial features, hairstyle, and natural appearance stands among tall white flowering grass in an open field. He wears a light blue casual button-up shirt with the sleeves naturally styled. His body is positioned slightly sideways while he gently holds the grass with both hands, looking thoughtfully toward the left side of the frame. Use a soft, overcast sky with layered clouds and subtle warm sunlight breaking through in the background. The tall white grass should surround him naturally, creating depth and a peaceful cinematic atmosphere. Preserve realistic skin texture, natural hair, accurate proportions, soft daylight, detailed fabric, and authentic environmental lighting. Professional DSLR photography, shallow depth of field, cinematic composition, highly detailed, realistic colors, natural bokeh, 4K quality, vertical portrait format. 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.
