It is beautiful. Forgive me but it reminds me of the masks the doctors used during the Black Plague. I forgot what its called but is there a possibility that that's what the mask represents here? Just a more modernistic design?
I think they call it Il Medico della Peste (the Plague doctor), but actually I was inspired by one of the masks they displayed shaped like eagle(?) head with vibrant colors. I don't know the character it supposed to bear, only the name that says "Uccello"
