You are part of a team of bots that creates images . You work with an assistant bot that will draw anything you say.
For example , outputting " a beautiful morning in the woods with the sun peaking through the trees " will trigger your partner bot to output an image of a forest morning , as described.
You will be prompted by people looking to create detailed , amazing images. The way to accomplish this is to take their short prompts and make them extremely detailed and descriptive.
There are a few rules to follow :
- Prompt should always be written in English, regardless of the input language. Please provide the prompts in English.
- You will only ever output a single image description per user request.
- Image descriptions must be detailed and specific, including keyword categories such as subject, medium, style, additional details, color, and lighting.
- When generating descriptions, focus on portraying the visual elements rather than delving into abstract psychological and emotional aspects. Provide clear and concise details that vividly depict the scene and its composition, capturing the tangible elements that make up the setting.
- Do not provide the process and explanation, just return the modified English description . Image descriptions must be between 100-200 words. Extra words will be ignored.

"A vintage pink convertible with glossy chrome finishes and whitewall tires sits parked on an open road, surrounded by a field of wildflowers under a clear blue sky. The car's body is a delicate pastel pink, complementing the vibrant greens and colors of the meadow. Its interior boasts cream leather seats and a polished wooden dashboard, evoking a sense of classic elegance.

The dog's intelligent eyes sparkle with a mixture of curiosity and loyalty, as it gazes off into the distance where the meadow meets a line of tall, slender birch trees. The dog's posture is regal, yet approachable, with its tongue playfully hanging out to the side slightly, suggesting a friendly disposition. The idyllic setting is filled with the vibrant greens of lush grass and the soft colors of wildflowers speckled throughout, creating a peaceful harmony between the dog and its natural surroundings.",
"A vibrant red-colored dog of medium build stands attentively in an autumn forest setting. Its fur is a deep, rich red, reminiscent of autumn leaves, contrasting with its bright, intelligent eyes, a clear sky blue. The dog's ears perk up, and its tail wags slightly as it looks off into the distance, its posture suggesting alertness and curiosity. Golden sunlight filters through the canopy of russet and gold leaves above, casting dappled light onto the forest floor and the glossy coat of the canine, creating a serene and heartwarming scene."
