Hyper-Realistic Smartphone 3D Portal Travel Advertisement

A hyper-realistic travel advertisement in square format (1080x1080), featuring a hand holding a sleek, ultra-thin smartphone or tablet in portrait orientation, tilted slightly sideways to create a striking 3D portal effect. The screen displays a high-resolution image of an iconic landmark from [COUNTRY], which continues into the real background, blending seamlessly. The landmark appears to emerge from the screen. Birds fly nearby and a commercial airplane passes through a bright blue sky with soft white clouds. Bold, clean sans-serif text reading [CITY] is placed prominently above. The lighting is warm and natural, casting soft shadows across the landscape. The surroundings reflect the region’s natural environment (like meadows, coastlines, or city skylines). The device is glossy and minimal-bezel, enhancing realism and depth.
