QwenVL Prompting

Question - Help

hi im fairly new to comfyui read lots of posts on reddit and watched a lot on youtube .
I love QwenVl for enhancing prompts. but have only just found out (I'm sure you know but might help somebody) if you put (copied from a post on reddit)
"Refine and enhance the following user prompt for creative text-to-image generation. keep the meaning and keywords, make it more expressive and visually rich. Output **only the improved prompt text itself**, without any reasoning steps, thinking process, or additional commentary."
in the prompt box
then add your simple prompt
"a pixar 3d style small boy wearing shorts"
you get a ice fleshed out prompt like
"A Pixar-style 3D animated small boy with a joyful expression, standing in a vibrant, sunlit outdoor setting. He wears bright red shorts that flutter gently in the breeze, his bare feet planted firmly on warm earth. His golden hair is tousled by the wind, adding to the sense of movement and liveliness. The background features lush green grass, blooming wildflowers, and soft blue skies dotted with fluffy white clouds. A few birds fly overhead, enhancing the whimsical atmosphere. Soft sunlight bathes the scene in warm tones, casting gentle shadows and highlighting every detail with cinematic clarity. This image captures an innocent moment filled with pure imagination and playful energy—perfectly rendered in hyper-realistic 3D animation inspired by Pixar’s artistic vision."

but if you add an image say of a house as well as the prompt with just the same prompt you get

"A Pixar-style 3D animated small boy in a vibrant red cap and blue shirt, standing on a sunlit street corner with his arms outstretched, holding a colorful kite that glows softly under the bright sky. The scene is set against an idyllic suburban backdrop featuring charming yellow cottages, lush green lawns, blooming flowers, and mature trees casting soft shadows across the pavement. A brick wall runs along the front of the house, adding texture to the serene neighborhood atmosphere. The entire image exudes warmth, whimsy, and playful energy, capturing a moment of joyful childhood adventure."

hope this might help somebody

my workflow pretty simple if you don't want to use an image just bypass it
