Create a highly detailed adult coloring book page featuring a halfling bard playing a fiddle in a bustling tavern. The scene should be rich with intricate patterns and textures, showcasing the bard’s elaborate costume, the ornate fiddle, and the lively expressions of the tavern patrons. Include details such as tankards of ale, wooden tables, a roaring fireplace, and various items of tavern decor. The atmosphere should be warm and inviting, with an abundance of elements for coloring.
