Wow, here is an accomplished artist who is a master at using the design element of line to create his images! Rik Reimert is a Dutch illustrator based in Germany. He is in his late twenties and loves traditional medias and techniques. The first image below is of his grandfather. On his blog RikReimert you will find more wonderful portraits and other drawings. Notice how he creates his shade and shadow with a broad range of different values. I am intrigued by the variety of different textures and line weight he includes in his image.
This second image is the book cover for Celebrity Portraits. Check this out on Blurg.
