1.Get a collection of photographs, or take some in the poses you want.
2.Once processed, blow them up in size on a scanner or photocopier, or leave them how they are.
3.Use a lightbox or a sunny window and put the picture on there so the light shines through (It will work with photos, but black and white photocopies work better)
4.Place a sheet of plain paper over the photo and draw round the person, adding features and remembering to change the shape of the face and other points. (Eyes, hair, nose ect.)
5.Once done, colour or shade as you see fit.
Later on I'll give some tips on changing the face and costume out.
