Seen and liked at the Royal Society of British Artists 2016 exhibition at the Mall Galleries.

There were lots of other ones I liked, including all the Nicholas Verrall. One of them :

Bay of St Tropez, by Nicholas Verrall

The Verrall is 61 x 74 cm. And for real simplicity, but very effective, what about this one at 28 x 33mm :

Late Afternoon Light, Venice, by Christopher Miers

See lots of others here.
