Alright, so here they are. I promised Neta, my USk flatmate for 3 nights, that I'd post them:
Sketches from the 4th International Urban Sketching Symposium in Barcelona, July 2013.
Sketches are posted in their chronological order.
I did not meet as many people as I would have liked and I did not manage to splash as many sketches onto my sketchbook paper as I had planned, but I gave it my best.
