Watercolor Fantasy Knight Redesign

Using REFERENCE_0 as the loose facial sketch and mood basis, reinterpret the character as a polished full-body fantasy character design sheet: change the close-up rough head sketch into {argument name="character name" default="Stefan"}, an elegant young male knight standing in a calm three-quarter pose. Clean up the messy construction lines into refined anime-style line art, preserve only the delicate eye-focused beauty of the reference, and redesign the rest from scratch.

Additions and transformation: create exactly 1 full-body character, exactly 1 long sword held point-down in front of him, exactly 1 flowing blue translucent cape, and exactly 1 ornate white-and-navy knight outfit with silver armor accents. Give him long flowing silver-gray hair, a composed confident expression, and a slim princely silhouette. Outfit details should include layered white tunic panels, navy underclothes, belts, gloves, tall boots, shoulder armor, forearm armor, gold filigree trim, and star-like decorative clasps.

Style: convert the rough sketch into a clean, softly colored watercolor anime illustration with delicate pencil-like outlines, pale washes, subtle texture, and high-fantasy elegance. Use a light misty background with no scenery, no text, and no extra characters. Keep the composition centered on a vertical canvas, showing the entire figure from head to boots.
