ELI5: Why the Mona Lisa is so famous?

It just seems like some painting to me, why is it such a big deal?

Well, to start, the Mona Lisa was painted by one of the most iconic figure in the times of the Renaissance which is Leonardo DaVinci. His anatomical studies of humans by examining and dissecting human cadavers and the Phi ratio (eg. the Vitruvian Man) has been used in his paintings, accurately representing the human body with near-perfect anatomical accuracy. It also introduced the three-quarter pose portrait layout. Previous paintings looked more stiff while the three-quarter pose used on the Mona Lisa looked more lifelike. Also, prior artworks had the same level of detail of the background and the subject. In the Mona Lisa, the background was more out of focus and the level of detail is significantly lower than the level of detail used on the subject, thus making it look like it was painted in the painter's POV.
