Elf Mage-Knight Character Design

Create a full-body high-fantasy anime character concept illustration on a clean off-white background: one young male elf mage-knight with pointed ears, {argument name="hair color" default="sandy blond"} tousled layered hair, sharp amber eyes, and a confident slight smile. He stands in a relaxed heroic pose, body angled slightly left, head facing forward; his left hand is raised palm-up conjuring one glowing golden astrolabe-like magic sigil, while his right arm holds one large ornate spellbook at his hip. Outfit: an elaborate royal mage armor ensemble in {argument name="main outfit colors" default="deep navy blue, burgundy, white, and metallic gold"}, with one high-collared long coat, one flowing split cape with burgundy lining, layered shoulder armor on both shoulders, one prominent sun-compass chest emblem, one wide belt with pouches, fitted trousers, armored gauntlets, knee guards, and white-and-gold armored boots. Include exactly three main celestial motifs: a golden compass/sun emblem on the chest, a matching emblem on the spellbook cover, and a floating circular magic diagram beside the raised hand. The spellbook is burgundy leather with gold corners, geometric trim, and a raised compass symbol. The magic sigil is made of concentric rings, compass points, tiny stars, and fine radial linework, glowing softly in warm gold. Use elegant Japanese RPG character design aesthetics, crisp ink-like line art, refined cel shading, delicate watercolor texture, intricate gold filigree, slim heroic proportions, and no text, logo, watermark, or background scenery.
