Create a detailed, square pixel-art image showcasing a fantasy warrior character in three distinct gear sets, each placed in its own horizontal row. Each row includes exactly six poses: Idle stance, Sword Attack, Magic Spellcasting, Defensive Block with Shield, Running, and Victory Celebration. Top Row (Starter Gear - Earth Tones): Simple leather and cloth armor in muted browns and greens, iron sword, basic wooden shield. Middle Row (Knight's Gear - Silver and Blue): Polished steel armor featuring silver plating with deep blue accents, helmet with closed visor, decorative longsword, ornate kite shield, flowing blue cape. Bottom Row (Mythic Gear - Gold and Crimson): Magnificent golden armor richly adorned with glowing crimson gemstones and fiery embellishments, flaming enchanted sword, translucent crimson magic shield, surrounded by a subtle, mystical aura. Ensure the warrior's proportions and facial features remain consistent across all poses and gear sets. Each set should clearly illustrate a progression in design complexity and visual appeal. Render each pose individually with a transparent background, neatly arranged in three horizontal rows within a square composition.
