Often what you leave out can make or break a painting. I left a single tree out (it was one third in from the right) and the composition just looked out for itself.
Also, it painted itself pretty much - it was finished within two hours, leaving us time to walk along the water's edge a little ways. There were many Alfrescoes out this morning, I'd say about 30 to 40 (there are 80 artists on the email list).
