Create a highly detailed, vibrant clipart illustration of a black and tan coonhound lying on grass, resting its front paws on an American football. The dog’s fur is sleek and glossy, with black as the primary color, accented by bluish-gray tones around the head and ears, and orange-brown highlights on the muzzle, paws, and legs. The dog is wearing a cozy orange scarf with white stripes and three bold white stars. The scarf should appear thick and knitted, with natural folds. The football in front of the dog is a classic brown American football with white laces and a white stripe. In the background, include a bright yellow football goalpost with thick, sturdy vertical posts and a horizontal crossbar, painted in metallic yellow, with subtle 3D shadows for realism. Surround the scene with small orange and white celebratory dots for a festive atmosphere. The dog is lying on detailed green grass, and the entire design should be sharp, with fine linework, vibrant colors, and a transparent background, suitable for T-shirt clipart. No text should be included."
