More sketches of people on the trains and tube. Some of the key elements to really get a resemblance can be intense observation and trusting your hands to put down exactly what your eyes see. I must say, for public transport sketches of people, each artist has to find a "personal shorthand" way of editing the vast information you see in faces and just highlight the essentials. Easier said than done. This is something I constantly struggle with!
Apologies for some of the poor images, I have been battling with my scanner of recent.
