BMW Performance Social Poster

Create a 4:5 aspect ratio, ultra-high resolution vertical social media poster with 8K print quality clarity. Refer to the reference image.{argument name="car model" default="BMW"} Using the reference image as the main element, and adopting its background structure and composition, this design was transformed into a BMW-themed design. All black tones were replaced with a completely flat surface.{argument name="background color" default="High-saturation BMW Blue"} Background. Maintain consistent layout, spacing, visual balance, and poster composition with the reference image. The background should have a smooth gradient, transitioning from a light electric blue at the top to a deep navy blue. Add subtle graininess (2% to 3%) and a subtle rectangular overlay (2% to 4% opacity). Keep the image clean, graphic, sophisticated, and non-realistic. Add soft touch shadows under the car. Use the same BMW from the reference image, only making changes.{argument name="paint finish" default="Matte Frozen Blue"} Alternatively, a deep metallic navy blue paint finish. Retain the original body shape, wheels, stance, and design details from the reference image. Show the car from a rear 45-degree angle, perfectly matching the reference image. Use a slightly elevated camera angle. Position the car slightly to the right center. Include the visible carbon fiber roof, aggressive rear diffuser, clearly controlled reflections, and detailed brake details. Maintain the exact same composition as the reference image: Top: Brand logo; Middle: Oversized font; Center: Car and text overlapping; Bottom: Editorial section and specifications. Typography: Main title: "BMW," in an ultra-compact, bold sans-serif font, vertically stretched, consistent with the reference poster. Color: Deep navy blue or near black. Static text, no distortion. Serves as a structural background. Subtitle: "BMW M4 G82," in a thin font with wider letter spacing. Logo area: BMW round logo centered at the top. Editorial section: Title: "BMW — Where Driving Becomes Instinct"; Body text focuses on: driver connection, handling, performance, and precision. Use the same box-style editing layout as the reference image. Background fade-out text: "M4", large scale, 3% to 5% opacity, positioned behind the text box. Bottom left: "M4 G82"; Bottom right: Specifications: 405 kW / 550 PS, 3.4 s, 307 km/h. Lighting should be clean studio lighting with sharp but controlled highlights. Color grading should use deep blue, high contrast, and pure black. Camera lens: 50mm, slightly raised at a 45-degree rear angle. Atmosphere: Performance, precision, driver focus. Add a bottom right watermark: harboriis, with a small x and an Instagram icon.
