"Create a highly detailed, vibrant clipart illustration of a black and tan coonhound sitting on grass, holding an American football with its front paws. The dog’s fur is primarily black with bluish-gray tones on its face, ears, and paws, accented by orange-brown highlights on the muzzle, paws, and legs. The dog is wearing a large orange scarf with white stripes and three bold white stars. The scarf should have a cozy texture, with natural folds and shading. The football is a classic brown American football with white laces and a stripe. In the background, include a yellow football goalpost with thick, sturdy vertical posts and a horizontal crossbar, painted in metallic yellow. Add subtle 3D shadows to the goalpost to make it appear realistic and rooted in a grassy field. Surround the scene with small orange and white celebratory dots to give it a festive, lively atmosphere. 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." This prompt captures all the detailed elements from the image, from the dog’s unique coloring to the realistic goalpost and scarf design. Let me know if you'd like any modifications!
