Leverage style presets or theme consistency: if you are doing a brand campaign or series, keep style consistent. seedream 4.0 helps in that.
Use reference images smartly: supply images showing lighting, style, color palette; helps seedream understand what you want.
Refine prompts: start with a strong base prompt, then add specifics: mood, lighting, composition.
Batch generation when possible: generate several variations to compare, then pick/edit the best.
Iterative editing: use the editing features to tweak small issues rather than trying to get perfect on first go.
