Create a stylized, decorative illustration of an echidna, blending intricate line work with vibrant, flowing colors. The echidna’s face and upper body should be detailed with fine, hand-drawn black ink patterns, giving it a delicate, textured appearance. Its small, inquisitive eyes should stand out, adding depth and personality. The spines and lower body should transition into a soft, watercolor-like gradient, incorporating warm earthy tones—rich browns, deep golds, and subtle oranges—with hints of metallic highlights. Ornamental botanical or geometric patterns should be woven into the design, enhancing its whimsical and folk-art aesthetic. The background should be dark or neutral, creating a striking contrast that makes the artwork feel bold, elegant, and nature-inspired. The final composition should be a unique blend of fine detail and artistic abstraction, evoking a sense of wonder and movement.
