One of my favourite artists is Edward Seago who died in 1974. His simple yet effective watercolours are a delight to behold.
Sometimes when teaching a watercolour class I demonstrate Seago's techniques for the pupils to try and emulate. His methods are not as simple as they look, however it's still worth attempting to copy a Seago to try and learn from the master.
I've been to Venice on numerous occasions and painted scenes like this working directly onto hand made paper with my brush loaded with colour.
