Dear Chris, thank you so much for the class, it brought a new approach to my drawing process and helped me to introduce various colours to the drawing more freely. This is the second drawing I've done, but still the portrait seems to me a bit flat and deprived of liveliness. I would be glad if you give some critique to my work, so I could understand what I do wrong.
