AI Prompt for Dramatic Sci-Fi Tech Banner with Alien Landscape

"Create a cinematic sci-fi landscape poster in a wide 16:9 aspect ratio. The scene shows a lone human silhouette standing on a rocky shore in the lower center foreground, facing a vast reflective mountain lake surrounded by dramatic jagged alpine peaks. Above the horizon is a deep teal-blue night sky with misty clouds, a huge glowing Earth-like planet dominating the upper center background, and one smaller moon near the upper right. Use atmospheric fog, high contrast, cool cyan and dark navy color grading, soft bloom, realistic digital matte-painting style, epic fantasy scale, slight depth-of-field blur, and a mysterious adventurous mood. Overlay large bold white sans-serif title text across the center reading {argument name="main title" default="GPT image 2"}, with subtle dark drop shadow; place a smaller bold white Chinese subtitle centered beneath it reading {argument name="subtitle text" default="更强大的图像生成模型"}. Keep the typography clean, modern, and highly legible, like a tech launch cover banner."
