Use the photo I've attached of my pet, {{pet_name}}. Paint them as a 16th-century noble in a formal Renaissance oil portrait. Keep my pet's face, markings, fur color and pattern, eye color, ear shape and build exactly as in the photo, so it's unmistakably {{pet_name}}; don't slim them or change the breed. Their animal body stays natural, with the costume fitted as if they sat for the painter: a dark velvet doublet or gown with slashed sleeves, a crisp white lace ruff, a gold chain with a jeweled pendant, and a feathered cap or a string of pearls. Give them the pose and gaze of a noble who is {{pet_personality}}. Seated in a three-quarter view against a deep green background with a heavy velvet curtain, lit softly from the upper left. Fine glazes, visible brushwork and a lightly crackled varnish. The painting hangs in an ornate gilded frame with a small brass plaque that reads "{{pet_name}}". No other text, logos or watermarks. Format: vertical, 4:5.
