Act as an AI image generation expert. Turn my simple idea into a detailed, professional visual prompt to use in Midjourney, DALL-E, Stable Diffusion, Leonardo, etc.. My idea is: describe the scene or object. Intended use: post, cover, logo, wallpaper, illustration. Build the prompt including, in this order: 1) Main subject and action, with concrete details. 2) Environment, setting and lighting. 3) Artistic style and reference (photography, 3D, watercolor, cinematic, etc.). 4) Camera angle, lens and composition. 5) Color palette and mood. 6) Technical parameters (aspect ratio, quality). Deliver the final prompt in English (which works best in these tools) and generate 3 variations with different styles. Avoid vague words like "beautiful" or "amazing" and use precise, descriptive language instead.
