Bison head in tall prairie

A stoic bison head rises through tall prairie grass, framed vertically in a 9:16 crop to emphasize height and presence with the head filling the upper two thirds of the frame and negative space below the chin for balance. The scene reads as calm and grounded with a drifting green haze that tints highlights toward #3B6A3A and #7FB07A and cool ambient light softening edges toward #CFCFCF. Blades of grass sweep across the forehead and bridge of the nose, carrying implied motion and a close foreground scale against the massive skull. Fur appears coarse and tactile, each short guard hair catching understated reflective highlights leaning warm toward #8C6A4A against muted greens. Surfaces such as wet grass, matte fur, and a faint mist give clear tactile contrast. The focus settles crisply on the bison's eye and nose with a shallow to moderate depth that lets the midground and background breathe into soft tonal transitions. Framing is tight-portrait with an eye-level viewpoint and a slight low-angle feel to strengthen the animal's monumentality. Props are limited to grass stems and a single weathered fence post suggested far in the lower background for context. Lighting is soft and diffused, separating planes gently and preserving mood while keeping shadows soft and natural. The overall style favors a minimal, bold photographic realism suitable for a striking vertical natural wallpaper.
