What type of figurative language is this?

While the part of the statement “I see the whole world in your eyes” is a Hyperbole, the second part is direct statement. The third statement too has a Hyperbole “I pour my heart into your hands” while “I have a song in my heart” is a Metaphor where the heart is compared to a book or a singer. However, the final statement seems a Simile as there is a like and the situations have been compared using the word “like.”
