How to Draw Donald Duck - Tribal Tattoo Design Style

How to draw Donald Duck in a tribal tattoo design style. I first roughly draft out Donald Duck and then erase the lines just enough so I can still make out the lines then I go in and add more detail.. I do this a couple of times until I am happy with the layout. Once I'm satisfied I erase the lines again then work in some tribal marks... Materials used: 110lb card stock, HB pencil, fine line pen, kneaded erasers
