有機的な菌糸で描くネオンアクセントのスカルTシャツデザイン

urban mystical tattoo-style t-shirt design, centered medium print, human skull formed entirely by organic mycelium roots, roots twisting and connecting to create the skull structure, hollow dark eye sockets, subtle mushroom growth emerging from the top and sides, strong black tattoo outlines, high contrast, off-white base with neon green and subtle purple accents, gritty texture, distressed ink, underground aesthetic, no text, balanced composition, looks alive and slightly unsettling, organic and raw, not perfect, premium streetwear design
