Anyone wishing to draw pics and scan'em in use a ruler and make the frame you draw the head in 2,17cm x 2,17cm, around the 25-55mm in the middle is the front(face), a good idea to make it exact is to draw three long-oval-ish shapes that DO cross each other aswell as two half of these shapes in the edges as that's the ends that are the back, after you've drawn your face just ink the lines you want to keep and erase the annoying little oval-ish shapes, then just scan the drawing into you computer using some sort of scanner and open the file in whatever program you use
