New York City-based artist Nicolas V. Sanchez (previously) creates masterful drawings with only the aid of a few ballpoint pens, rendering unbelievably realistic portraits and still lifes in his many sketchbooks. Due to his precise application of highlights and shadows several of his works seem three-dimensional, such as the fruit bowl seen below which looks placed on the page and not drawn.
Sanchez is also a talented painter, working with oil to create blurred familial scenes on canvas or linen. You can see more of his sketchbook-based ink drawings, and browse his collection of paintings, on his Instagram and Facebook.
