This project was one that took the most time as it was one I wanted to make look really good and very detailed.  I created this project detailed down to each hair on my beard drawn separately and as a whole, held over a thousand layers.  This project was made by taking a picture of my face, editing it in Adobe Photoshop to eliminate blemishes and imperfections, taking that project into Adobe Illustrator to draw over with the different shapes to create my face in it's own design.
Both are extreme close ups of the right eye on the illustration above and are examples of the detail used in this project.
