My idea is to recreate Mona Lisa. If by recreate you mean to make it your on, I was thinking you whould make it in Picasso's artform of making everything shapes. I would imagine that'd be cool. If not, I still think the Mona Lisa is cool. Of you don't like the Mona Lisa, there is also Starry Night and that's pretty popular too.
Poussin was fascinated by ancient Rome and Italian Renaissance cultures. In his Et in Arcadia Ego that fascination has been translated into a visual text illustrating rational order and classicism. It is reminiscent of which of Raphael.
