Create a single image divided into four equal sections in a portrait layout featuring the same elf boy. The boy has sky-blue hair and carries a backpack full of stuff in the fantasy world. Each section should highlight the character in one of the four specified expressions and poses: Smiling gently, Laughing heartily, Looking disappointed, and Showing determination and enthusiasm. Ensure that each expression and pose is distinct and clearly different from the others, with each section clearly defined and separate, with no overlap. --niji 5 --s 750 --style 3zRNcMMvQsBT6BKgA53RVZ --seed 2047968834
