Day 13 and economy of line

I think I well and truly broke in my new sketchbook…nine pages so far today. Pretty good, right? All of it public transport drawing so mostly backs of heads and profiles yet again. Plus another of London Bridge Station but different viewpoint. All completed in pen (of varying shades). I like drawing in pen, it forces you to be decisive with your strokes, so that each one counts. I did one of a kid, but it was unfinished as he realised that I was drawing him and then became rather stilted. People are only good when they are unaware, then they are more natural in their posture. Hence the back of heads.

This one was daydreaming out the bus window.
