SNS・広告代理店向けバナーAI画像生成ツール

Design an ultra-high-resolution hero image or social media banner for a 'Creative Agency' called '[AGENCY_NAME]', promoting their services '[SERVICE_TYPE_1]' and '[SERVICE_TYPE_2]'. The image features a modern, abstract composition with dynamic geometric shapes and gradients in a vibrant color palette (e.g., '[COLOR_PALETTE]'). A central, slightly off-center focal point could be a stylized icon representing 'creativity' or 'innovation'. Use dramatic, high-contrast lighting with an emphasis on luminous, glowing elements that cast subtle shadows to create depth, reminiscent of digital art or futuristic tech interfaces. The style should be sleek, professional, and visually striking, inspired by contemporary graphic design trends and high-tech advertising visuals. Rendered in 3D software for crisp edges and realistic textures, ensuring 4K clarity. The atmosphere is innovative, energetic, and sophisticated, designed to capture attention and convey cutting-edge capabilities. Ample negative space is left for prominent text overlays such as '[CATCHY_HEADLINE]' and a call to action like 'Visit Our Website'. The emotional tone is inspiring and forward-thinking. Quality ultra, ratio 16/9.
