98 "A graphic design poster with a futuristic sci-fi aesthetic, 1:1 aspect ratio. The central subject is an abstract, organic-synthetic alien bust featuring a translucent, glowing glass-like helmet overlay on top. The head has a misty, semi-transparent outer shell housing a fluid, swirling inner core of vibrant glossy orange, deep purple, and polished chrome. No eyes or mechanical lines. The background is a warm, soft peach-colored canvas. At the top, bold black futuristic typography reads \"NANO BANANA 2\". Modern editorial layout with elegant design, high-contrast atmospheric lighting, and minimalist UI text elements referencing ComfyUI workflows. Sophisticated art-tech style with a misty, dreamy, and highly artistic design feel.",
