Backlight
Light arriving from behind a subject can separate its outline, illuminate translucent materials or create a silhouette.
Prompt
Use Backlight: light the existing character from behind so the hair and shoulders have a clear illuminated edge, while the front remains darker but readable. Keep the background brightness subdued and controlled separately.

Effect comparison
In the baseline image, Biwa's front is visible but the hair and shoulders have relatively little separation from the dark corridor. The backlit version adds a warm, bright outline to the top of the head, strands of hair, both shoulders and coat edges while retaining darker clothing detail on the front. The rear light separates the figure from the background, and the bright outline together with the darker front indicates the source's position.
