Create a 4:5 vertical social poster in ultra high resolution, 8K print quality sharpness. Use the BMW car from the reference image as the main subject and use the background structure/composition from the reference image, but transform it into a BMW themed design. Replace all black tones with a flat high-saturation BMW blue background. Keep the same layout, spacing, visual balance, and poster composition from the reference image. Background should use a smooth gradient from slightly lighter electric blue at the top to deep navy blue at the bottom. Add subtle grain texture (2 to 3%) and faint rectangular overlays (2 to 4% opacity). Keep it clean, graphic, premium, and non-realistic. Add a soft contact shadow under the car. Use the same BMW from the reference image, changing only the paint color to matte frozen blue or deep metallic navy. Keep the original body shape, wheels, stance, and design details from the reference image. Show the car in a rear 3/4 perspective matching the reference image angle exactly. Use a slightly elevated camera angle. Position the car slightly right of center. Include visible carbon roof, aggressive rear diffuser, sharp controlled reflections, and subtle brake details. Keep composition identical to the reference image: Top: branding Middle: giant type Center: car overlapping text Bottom: editorial block and specs Typography: Primary text: “BMW”
