At last! The result of hard work of three months: I started working on Arlecchinno in the beginning of April. My Arlecchinno in his full glory! The most challenging work that took most of the time was his costume. Of course, it is my own interpretation of the classic character. Mine Arleccinno much more childlike and naive.
But in my research I actively used this wonderful site:
I found the summary of classic "Commedia Del'Arte" extremely interesting and full of useful information.
A little latter, I still plan to add traditional "Arlecchinno"s mask to his costume.
