This image would be fairly easy to complete in Illustrator. The woman’s face can be used with the pen tool and making curved vectors and making sure that it’s not exactly perfect so it comes out slightly abstract. These curved vectors can be used for all part of the face. Even the shadows on her face can be made with the pen tool. Her hair can be made with drawing curved lines. The color in her lips and eyes can be used with the paintbucket tool and the color in her hair along with the color in the back are all used with the pen tool and making vectors. The very background color could be made with the shape tool. The colors’ opacity has been altered and the vector shapes overlapped to get a more abstract look.
