About Myself

• Being from the second biggest island of Italy, Sardinia... the Mediterranean climate has influenced my life completely. I love the sun and the clear blue water! But even if I belong to this Paradise I cannot swim! This will be my next big goal after I overcome my fears for small-medium insects! I enjoy eating every kind of food, but my favorites are my mom's Lasagne and the Sardinian cheese melted by my dad on the fireplace.
• My main interest is Photography and I enjoy Black and White portraits as well as shots in urban settings.
