New sub-prompt text...Create an ultra-realistic premium wall-mounted shop sign mockup using the uploaded logo as the only brand artwork. Place the uploaded logo prominently and naturally on the front face of a large elegant rectangular sign attached directly to an upscale storefront wall, keeping the logo exactly unchanged with its original proportions, shapes, typography, colors, and details. The sign should feature a clean ivory or soft-white surface with realistic depth and a premium metal border. Automatically sample the dominant color from the uploaded logo and apply that brand color to the sign's outer border, side thickness, mounting brackets, and other colored structural elements, ensuring the color changes according to the uploaded logo rather than using a predefined color. The logo must look physically printed or professionally mounted onto the real sign surface, with realistic material interaction, subtle texture, natural perspective, accurate shadows, and believable reflections. Show a sophisticated commercial building exterior in natural daylight with soft environmental shadows and a slightly blurred background, creating the appearance of a genuine professional storefront photograph. No additional logos, fake text, watermarks, or unrelated graphics.
