Create an artistic representation of Andrew Lloyd Webber musicals using a unique art style suitable for Tumblr artwork and collage. The artwork should capture the essence of Lloyd Webber's iconic musicals, such as 'The Phantom of the Opera,' 'Cats,' and 'Jesus Christ Superstar,' while incorporating elements of fantasy, drama, and theatricality. Emphasize vibrant colors, surreal imagery, and intricate details to evoke the rich storytelling and emotional depth of the musicals. Feel free to experiment with mixed media, digital effects, and unconventional composition techniques to create a visually striking and memorable collage artwork.
