Ensure that the image does not include any other characters or superheroes besides Superman. Avoid any elements that may make the image appear too mature or serious, as the focus should be on Superman's youthful charm. Additionally, avoid any alterations to Superman's costume, such as changes in color or design. Stick to the classic blue and red costume with the traditional "S" emblem. Finally, avoid any overly exaggerated or disproportionate features. Keep the proportions consistent with Toriyama's style, with a cute and charming interpretation of a young Superman.
