Smartphone Template Mockup

Prompt Asset: Generate a hyper-realistic image of a smartphone standing upright on a gradient yellow surface, with its screen facing forward and slightly tilted to the right. The phone's frame should be sleek and metallic, reflecting a greenish tint on its left side and a golden hue on its right side. The screen should display a transparent checkered pattern, indicating a blank or template state. The background should be a warm, gradient yellow wall that transitions from a lighter shade at the bottom to a darker shade towards the top. The lighting should be soft and natural, casting a subtle shadow of the phone on the surface below, with a hint of green reflection on the left side of the shadow. The overall atmosphere should be modern, minimalist, and studio-like, with a focus on showcasing the phone's design and the empty screen. The image should be highly detailed, with realistic textures and subtle color gradations. The phone's metallic frame should have a high-gloss finish, and the surface it stands on should have a matte finish. The checkered pattern on the screen should be clearly visible, with a subtle gray and white checkerboard design. The image should be free of any watermarks, logos, or other distractions, and should be suitable for use in a high-end design editorial or campaign photograph.
