"Create a full-body 3D model of a black sheep with a rebellious personality, dressed like a 90s rapper. The sheep should have dark, woolly fur with a slightly messy and unkempt look. Emphasize its defiant nature through its posture--standing confidently with a slight tilt to its head. Dress the sheep in classic 90s rap attire: a baggy tracksuit with bold colors, a gold chain with a large medallion around its neck, a backwards baseball cap, and oversized sunglasses. The expression should be bold and determined, with a hint of mischief in the eyes. Ensure the design is versatile for future variations, allowing different outfits and accessories to define unique personalities within the 'black sheep' theme. Capture the entire body of the sheep in the frame."
