It seems that sketching indoors has pushed me to try new compositions that focus on groups of people rather than on the overall streetscape or individual subject. Although this was probably the largest number of people that I've ever fit inside any of my drawings, I still feel that I wasn't quite able to capture how populated and vibrant that place really felt.
As a slow sketcher, I'm still struggling with my bias towards recording the "easy targets" - the stationary elements of the crowd that give me enough time to be drawn in "sufficient" detail. I'd be very interested in hearing other sketchers' thoughts on drawing crowds and "populating" a drawing.
