From my second notebook. This is Portugal dos pequeninhos, a park in Coimbra where they've got Portugal main buildings built at small scale. Cool place, if you ask me!
These sketches are way back from my very first travel sketchbook. I did them mostly from the car or while I walked from one place to the next and I was absolutely oblivious to any kind of technique I could use to just draw faster. They are very crude and I don't know exactly what came into me to start doing these doodles during that trip to the Pyrenees, but I haven't stopped ever since :D
