Worldbuilding Scene Concept Art: The Three-Act Space of Withered Tide Harbor

Aimed at "visual exploration of worldbuilding and atmosphere," this piece uses the scene concept art capabilities of Seedream 5.0 to establish a set of reusable environmental visual anchors for the fictional coastal city-state "Withered Tide Harbor." The creative path is to first give a main prompt describing the world's rules and tone, then use a reference image with an already-determined atmosphere as a structural master, letting the model derive a second-act variant while preserving the spatial skeleton and color logic—this is precisely the typical use of image-to-image reference in the concept design workflow: set the tone first, then expand within the same spatial language. The work consists of two tracks: the main image handles the overall worldbuilding tone (giant shipwreck architecture after the low-tide line recedes, salt-eroded stone structures, dusk side backlight), while the reference-derived image reuses that image as image input, adding temporal and weather variations, to test the model's performance on cross-shot consistency. The size in the schema is set to 2K to balance detail and generation efficiency, watermark remains off by default, and optimize_prompt_options uses standard mode. Applicable scenarios: mood boards for game and film pre-production art, scene concept exploration, consistency testing of series visuals, and production workflows that need to quickly lay out multi-act spaces with a small number of reference images. This topic is suitable for creation with the Seedream 5.0 model family; storyboard requirements involving cross-shot character and scene consistency can also be extended along the same path.
