This present workbook aims to provide 10 drawing lessons to aspiring draftsmen or beginning draftsmen, and may also add to the repertoire of experienced draftsmen, as they obtain forms from my drawing process here. In "Ten lessons for drawing portraits", drawing enthusiasts will find classes that teach from the basic strokes to compose a portrait, shapes and proportions to step-by-step examples for drawing portraits. 
The lessons were prepared by me with care and with the intention of providing the basic elements to help aspiring draftsmen. Despite being lessons focused on portraits, they can be used in general for drawing as a whole. 
The Digital Book comes with a second Ebook called "Drawing a portrait in profile", as an extra bonus. 
I wish you all good practice!
