Mottisfont is a National Trust estate near Romsey in Hampshire. My reference photos are from early March, when there were no leaves yet on the trees.
Having painted them now (in April), I thought it would be nice to show the trees in blossom. This way, they make a nice contrast to the buildings in the background and generally stand out more from the other elements of the painting.
I have also moved the trees in the foreground closer together than they are in real life so they make a repeating pattern. In short, this painting is not a literal description of the place but how I feel about it.
