Create a stylized, decorative illustration of a kangaroo, blending intricate line work with vibrant, flowing colors. The face and upper body should feature fine, hand-drawn black ink patterns, giving it a detailed, textured appearance. Its strong, expressive eyes should stand out, adding personality and depth. The lower body, powerful legs, and tail should transition into a soft, watercolor-like gradient, incorporating warm earthy tones—deep oranges, rich browns, and golden yellows. Ornamental botanical or geometric patterns should be woven into the design, enhancing its whimsical and folk-art aesthetic. The dark or neutral background should create a striking contrast, making the artwork feel bold, elegant, and dynamic. The final composition should be a unique blend of fine detail and artistic abstraction, capturing the energy and spirit of this iconic Australian animal.
