I'm not one to vector myself over and over again. In fact my last self portrait was in 2009. I thought for fun I'd vector myself in a daft pose. Thus starting my "Quirky Selfies" project, featuring many of my friends... and eventually, a tutorial.
And below is the end result from the tutorial I've written about this style and project, over on Envato Tuts+: How to Create a Quirky Line Art Portrait in Adobe Illustrator.
