Why to like the Mona Lisa photo?

The Mona Lisa, by Leonardo Da Vinci is not only one of the most important paintings ever created, it was one of the most important to Leonardo himself, a work he spent more than four years on and carried with him everywhere he went for the remainder of his life. The Importance of the Mona Lisa to Leonardo has caused great deals of speculation as to why he might have painted it and what the painting might be depicting.
This figure of a woman, dressed in the Florentine fashion of her day and seated in a visionary, mountainous landscape, is a remarkable instance of Leonardo's sfumato technique of soft, heavily shaded modeling. The Mona Lisa's enigmatic expression, which seems both alluring and aloof, has given the portrait universal fame.
From the beginning it was greatly admired and much copied, and it came to be considered the prototype of the Renaissance portrait. It became even more famous in 1911, when it was stolen from the Salon Carré in the Louvre, being rediscovered in a hotel in Florence two years later. It is difficult to discuss such a work briefly because of the complex stylistic motifs which are part of it. In the essay ``On the perfect beauty of a woman'', by the 16th-century writer Firenzuola, we learn that the slight opening of the lips at the corners of the mouth was considered in that period a sign of elegance. Thus Mona Lisa has that slight smile which enters into the gentle, delicate atmosphere pervading the whole painting. To achieve this effect, Leonardo uses the sfumato technique, a gradual dissolving of the forms themselves, continuous interaction between light and shade and an uncertain sense of the time of day.
