Style guide
Every art style the studio can paint, with real cards made in it. Each example shows the words that were typed, the picture that came out, and the prompt the style builds from them.
Separate from the art style, the studio also picks what the picture is of. Places default to a scene, things to an object, phrases to an illustration, and everything else to a portrait.
Render as a centered head-and-shoulders or upper-body PORTRAIT of a character that personifies the concept — expressive face, strong likeness, painterly detail.
Render as a single iconic OBJECT or artifact that symbolizes the concept — detailed, tactile, centered, with atmosphere and lighting that match the chosen art style. No people.
Render as a real LANDSCAPE / STREET / PEAK photograph of the named place — daylight or golden hour, identifiable architecture or terrain a local would recognize, natural color, atmospheric depth. Figures if any are tiny and incidental. Not a portrait. Not a fantasy metaphor.
Render as a symbolic ILLUSTRATION — flowing shapes, layered metaphor and decorative motifs, drawn in the chosen art style. Lean stylized rather than photoreal.
