"Design a fun and whimsical Halloween sheet centered around the letter 'Q.' Make the letter bold and round, with a smiling face. Surround the 'Q' with cute Halloween elements: a quirky little queen witch standing beside the letter, a friendly ghost floating through the loop of the 'Q,' and a jack-o'-lantern resting at its base. Add festive touches like stars, a crescent moon, and scattered candy around the scene. with the letter 'Q' as the focus in this light-hearted Halloween design."
