''Trachide'' from the pacific Ocean

This drawing was made for a contest edited by the "ardea" association called "illustrare la natura" (illustrating nature)... It was the first drawing contest I ever partecipated, so it was a great surprise for me when I discovered that my drawing was selected to be a finalist... it was exposed for three days in the natural history museum in Naples... even if at the end of the contest it didn't win... I'm really really really proud of it.
Tcniques used: silver, blue black and white pencils on black cardboard, refined with white china
