Specifically, it targets the following elements:
* Overused comparisons: Shakespeare uses typical comparisons from traditional love sonnets, like comparing a woman's eyes to the sun or her breath to the sweet south wind, but then deliberately subverts them by saying his mistress's features are not as perfect as those images.
* Idealization: Traditional love sonnets often paint a picture of idealized beauty, but Sonnet 130 presents a realistic and unflattering portrayal of his mistress.
* False flattery: The sonnet mocks the practice of showering a beloved with exaggerated praise that is not genuine.
By presenting an honest and humorous take on his mistress's appearance, Shakespeare is subtly criticizing the artificiality and insincerity of many love poems of the time. He is suggesting that true love can exist without the need for extravagant or unrealistic descriptions.
