Create a full-length image of Superman with the body type of Velma Dinkley. Ensure he is wearing his classic Superman costume. Design the background to be a seamless blend of Metropolis and a classic library, incorporating elements like skyscrapers and shelves filled with books. The scene should evoke a sense of mystery and heroism, fitting for both characters. Make sure the lighting is balanced to highlight Superman’s features while maintaining the ambiance of both settings.
