Create a vertical 2:3 cinematic still with a restrained almost monochrome palette and fine film grain. The upper two thirds is a very pale cloudy gray blue sky with extensive empty space. In the center lower half, a black motorcycle and helmeted rider are suspended in midair, traveling left. Show the motorcycle in strict side profile. Its round front wheel hangs near x30%, y58%, slightly below the body, with a dark headlamp and curved fuel tank above it. The rider crouches forward over the handlebars, helmet around x50%, y39%, their body merging into a thick black plume. The rear half of the bike and rider breaks apart into smoky black wisps trailing horizontally toward the right edge. Preserve four narrow pale metallic horizontal streaks through the rear body. The smoke must look like soft particle dissolution, not fire or an engine exhaust pipe. A dark barren ground strip fills the bottom quarter. Layer low foggy mountains behind the bike on the right, with the nearest slope descending leftward and dissolving into light haze. No horizon buildings, road markings, spectators, text or bright color. Keep the rider and machine near black silhouettes with just small silver reflections on the front wheel and chassis.
