painting quickly in Verona

Occasionally I set out to make an architectural watercolour without doing a drawing first. I'm of two minds as to whether this is a good idea or not.

I did this one in Verona a few years back:

It's a lot sketchier than I prefer.

The buildings are among the many gothic survivals in Verona. I did the painting in the Piazza del Erbe - the old market, as the name implies. Through the arch you can see one of the Scaliger tombs (Mastino's, if I recall correctly). These are among the most spectacular funerary art of the entire Gothic era, but for some reason are underrepresented in both the academic and tourist literature.
