In this case, we made the tour in the castle Schönbrunn, just outside Vienna. We visited the rooms and exhibitions, and made a nice long walk though the park in the warm sun. We ended on a beautiful terrace with some nice cold icecoffee and a beer, in full view of the castle.
But drawing that facade would have been totally uninteresting, at least from where we sat.
So I decided to draw the icecoffee.
After all, it's less important what you draw, as long as it represents the memories of the place.
