This is my version of a photograph originally taken by the photographer Stephan Bollinger who gave me permission to include it in my portfolio. Please check out his work too!

First lines were roughly made in photoshop with the original image as a base.

The lines and original image were then imported into illustrator and the lines were done again by hand, this time with attention to conecting points. They were filled by eye with the average colour of the image they covered.
