<https://s.mj.run/Afj_LYVCrMc> Modify the illustration of a brindle dog by slightly lengthening the muzzle to resemble an American Staffordshire Terrier (Amstaff). Maintain the flat design style with simplified shapes and a limited color palette, ensuring the dog retains its strong, confident expression. Adjust the facial features to align with the typical characteristics of an Amstaff, while keeping the overall clean and modern aesthetic of the illustration.
