My mistress' eyes are nothing like the sun

In this poem by Shakespeare, Shakespeare recounts many of the negative qualities of his lover compared to many beautiful substances existing on the Earth. He accomplishes this through numerous instances of imagery and through the rhythmic flow of the poem. Each description comes one after another and rolls with a nice beat thanks to the Sonnets meter. The poem ultimately culminates in Shakespeare saying how despite her flaws and how she compares to things such as the snow and sun, he is truly lucky to have her as his love.
