I've been drawing self portraits for many years now but I nearly always draw myself with a blank expression on my face. I suppose it's just the way I look when I'm concentrating on my drawing but I usually end up looking the same. Tonight I thought I would try making some sketches of myself with different expressions. It sounds easy enough but in practice it proves a bit difficult. I quickly discovered that holding the expression for even just a minute is quite difficult. As a result the drawing has to take place quickly or in stages, with ample rest time between sessions of holding the "face" I'm drawing.
