提示词A medium close-up portrait of an original adult male botanist with thoughtful features, wearing a light, cream-colored linen jacket. He is positioned within a vibrant, sun-drenched greenhouse, surrounded by deep green foliage. The light is warm and dappled, streaming in from above, creating high contrast on his skin and the linen. His hands are just out of frame, suggesting activity. Medium: High-detail Photography. Palette: Rich greens, warm beige, and soft amber highlights. Intentional negative space is created by the bright, hazy background behind his head. Vertical 9:16 wallpaper; main subject in the lower-middle, quiet upper quarter for a lock-screen clock. Full-bleed artwork, no border, no frame, no text, no typography, no logos, no signature, no watermark.
