Milan-based Italian illustrator Marcello Barenghi posts videos of his photorealistic drawing process to his YouTube channel at the rate of about once a week. On his website, Barenghi lists varied influences, from Leonardo da Vinci to Derek Riggs, the illustrator that worked with Iron Maiden on their band and album graphics. Barenghi's amazing drawings seem to leap off the page when he is through. Follow the artist on Facebook here. Via Colossal
