Scooby Doo fan art rendered in vibrant digital colors, Shaggy's portrait takes center stage with a faded green t-shirt, fluffy light brown hair, and athletic physique, exuding a sense of toughness beneath his normally carefree demeanor, eyes locked in sharp focus, a single intense gaze piercing through dynamic lighting effects, ultra-detailed textures, post-processed for an immersive, cinematic feel.
