Reference-Image-Driven Scene Concept Art: Worldbuilding Atmosphere Exploration

Using a low-fidelity scene sketch as a reference image, leverage the reference-image guidance capability of qwen-image-3.0-pro to develop it into a conceptual atmosphere image ready for worldbuilding development. The approach is to write what to retain and what to change into the positive prompt: keep the compositional skeleton and subject placement of the sketch, and replace materials, lighting, and atmosphere; at the same time, use negative_prompt to constrain text watermarks and low-quality artifacts. On the output side, fix 16:9 and 2K settings, and provide a seed to make results reproducible under the same reference image and prompt. This is suitable for early-stage concept design direction comparison, storyboard atmosphere setting, and exploratory assets that need a consistent style as a group. There is only 1 reference image, within the model's input range of 1–3 images; prompts should be concise, avoiding piling up overly long descriptions.
