Worldbuilding scene concept art: Morning mist over ruined sanctuary

Using krea-3/text-to-image for a visual exploration of worldbuilding and atmosphere: from a single text prompt alone, fix the spatial narrative of "abandoned sanctuary + morning mist + massive scale" into one horizontal-format concept image, serving as a tonal reference for subsequent scene design. In planning, the compositional information is written into the prompt (scale contrast, depth layers, light direction, materials and color palette), stylistic noise is kept out in negative_prompt, variant=berry is used for better image quality, landscape_16_9 provides horizontal space close to a cinematic aspect ratio, and reasoning_level=medium lets the model first reason about and expand the prompt more thoroughly; a fixed seed makes it easy to fine-tune repeatedly under the same tone. Applicable scenarios: atmosphere exploration in film/game pre-production art, a tonal image for a concept art setting collection, and a starting point for subsequent image-to-image and editing iterations (for example, reusing this composition while replacing materials, lighting, or time of day). This input contains no reference images; the entire image is generated from the prompt.
