Create a premium, modern high-fashion CHARACTER CONCEPT ART SHEET in a 16:9 widescreen layout on a pure white background, following this exact structured composition and visual aesthetic:
[STYLE]: high-contrast digital anime illustration with clean, slightly textured graphite outlines, sharp cel-shaded shadows, and soft hand-painted watercolor textures. The style should feel like premium, highly fashionable dark-fantasy concept art, featuring a bold, expressive color-clash harmony of polished steel gray, tattered midnight-blue, and glowing celestial-blue.
[SUBJECT_DESCRIPTION]: A formidable, elegant knight protagonist wielding glintstone sorcery. He wears sleek, gothic-style polished steel plate armor with tattered midnight-blue draped fabric, a distinct steel sallet helmet with a thin vertical visor glowing celestial-blue, and gold filigree engravings on his gauntlets. In one hand, he wields a steel straight-sword, while his other hand summons floating, glowing celestial-blue magical swords that hover in a defensive arc around his shoulders. Swirling stardust and glowing blue magic runes orbit his armor, casting cool blue highlights across his steel plate.
Layout Composition (Organize strictly into these sections):
1. LEFT PANEL: METADATA & TURNAROUND
- Large, bold vertical typography of the character's Name in a clean, heavy sans-serif condensed font.
- Metadata Block: "ROLE", "CORE MOOD", and "VISUAL SIGNATURE" detailed in a clean sans-serif font.
- MINI TURNAROUND: 3 small, clean vertical figures showing "neutral", "back view", and "profile" stances.
- SILHOUETTE STUDY: 3 small, solid-black silhouette matchings of the turnaround stances underneath.
- EXPRESSION STUDY (Bottom Left): Exactly 4 small, close-up headshots showing subtle shifts in expression (e.g., Neutral, Pensive, Confident, Smile).
2. CENTRAL PANEL: THE CENTERPIECE
- One giant, dominant full-body figure of the character standing in a cool, relaxed signature pose (e.g., hands in pockets, looking down/aside). This figure must visually dominate the center of the sheet with maximum detail.
3. RIGHT PANEL: MULTI-POSE & THEMATIC STUDIES
- POSE STUDY: Exactly 4 to 5 small-to-medium figures in dynamic, casual stances (such as "seated", "crouching", "leaning", "low angle", or "top view"), each with a small handwritten-style descriptive label underneath.
- OPTIONAL SPECIALTY STUDY: A vertical strip of 4-6 artistic, painterly portraits with expressive brushstroke or paint-splatter borders showing morphing, stylized, or glitch-like variations of the character's face.
4. BOTTOM RIGHT PANEL: DETAIL STUDY
- Exactly 5 small square close-up crops highlighting the character's unique features, accessories, and textures (e.g., fabric weave, jewelry, specific utility pockets, unique footwear soles).
- Each crop must have a clean, neat handwriting-style label underneath describing the detail (e.g., braids medium length, layered fit, chunky sole).
Keep the entire presentation visually consistent, clean, and highly professional, mimicking a real studio-grade character design bible.
