Poster Geometrico Minimalista di Battaglia Equestre

Using the reference painting as the source composition, transform it into a minimalist, stylized geometric poster portrait. Preserve the rearing-horse equestrian pose, overall framing, dramatic [red] cloak, military uniform, horse direction, mountainous battlefield background, and intentionally obscured facial features. Replace the classical oil-painting style with clean flat-color vector shapes, sharp angular polygonal planes, simplified cel shading, and a limited palette of [deep navy, slate blue, cream white, tan, black, and vivid red]. Render the mountains, clouds, horse anatomy, billowing cloak folds, and rocky terrain into faceted polygonal forms with crisp edges and high-contrast graphic lighting. Simplify background soldiers and battlefield elements into small abstract silhouettes, including [5 small soldier silhouettes along the lower-left slope and one cannon wheel]. Remove all foreground carved text, with no text anywhere in the image. Vertical heroic composition with dynamic diagonal movement and a modern editorial illustration aesthetic.
