The copy of the Mona Lisa in the Prado museum, that was recently cleaned, offers a fresh view of what the original painting probably looked like before centuries of varnish, dust and soot covered Leonardo da Vinci's version. Plus the greenish bullet proof glass... The sfmanto technique of the master is evident, though I find the student copy (if that is what it is, one his apprentices in Leonardo's bottega/studio) did a very bad job with the eyes - the sitter's right eye looks a bit bigger and darker, and to close to the nose? More on my blog on how to make sure portrait eyes don't look cross eyed. Or, the sitter may have had one eye larger than the other, as I have encountered with sitters. Look on the Prado web site for more information on this enigmatic painting.
