I love everything related with Leonardo, so far your sculpt and concept is really cool and amazing executed, many people and experts thinks is Leo's face in the vitruvian man, it's common to visualize him as an old and grey hair man, but you did a really nice job wich approach us to see what was his face at his 30's, great work again Joaquin!
last summer I did a clay study of his classsic image, just would like to share
