Portraits 2.0 by Julio Cesar
Portraits 2.0 is a project that started as a way to study. A lot of illustrators do it, so Julio Cesar decided to practice. He wanted to improve his stroke so started to do these exercises using photos. Many of the illustrations are images of people he saw on Tumblr, Pinterest and Flickr, but some pictures are from his friends.
The core of the project is that people feel the thrill when they see the images. I wanted to make people excited and happy so I chose a style that is very cartoonish.
Practice every day, take courses (which helps A LOT), have true friends who will tell you when one of your drawings needs improvement or isn't good. Always try to improve, never feel like you know everything, try to organize and pursue your goals.
