Character Design

Change it to [an unexpected, unlikely Westeros character], located in a different but related place, and update the passport portrait, emblem and origin according to the character's actual history.

Passport-document layout with portrait, emblem and origin details.

Even document-photo lighting.

Use real Westeros locations, such as King's Landing, rather than '...Kingdom'.

Passport / identity document style.

Workflow: generate multiple candidates then do a best-of-N selection to avoid the instability of a single-shot generation.
