Personally, after having seen the Mona Lisa twice, I think I like it better.
Also, most are unaware, besides the Mona Lisa in the Lourve, there's a "Mona Lisa" by Leonardo in The Prado in Madrid.
The one in Madrid is believed to be painted by one of his pupils.
I like this one better, too. Never really got the attraction of Mona except for its idiosyncrasies. But then, I’m a fan of Rembrandt and Bierstadt.
