Portrait oil painting minimalist mountain

Using REFERENCE_0 as the composition source, transform the painting into a minimalist geometric poster portrait. Preserve the pose of the rider on a rearing horse, the overall composition, the iconic red cloak, military uniform, horse orientation, mountain battlefield background, and the deliberately blurred facial area. Replace the classical oil painting texture with clean solid-color vector shapes, sharp geometric facets, simplified shadows, and use a limited color palette of dark navy blue, slate blue, cream white, tan, black, and bright red. Treat the mountains, clouds, horse structure, cloak folds, and ground as clear-edged faceted polygons with high-contrast graphic lighting. Simplify all soldiers and battlefield details in the background into small abstract silhouettes; keep 5 visible small soldier figures and one cannon wheel on the lower-left slope. Remove the foreground text carved on the rocks, and do not add any new text. Maintain a vertical and heroic composition, presenting a dynamic diagonal sense of motion and a modern editorial illustration style.
