I found the work of John Piper today. I was happily surprised by many of his watercolour landscape sketches, mainly because I sometimes feel that my work is too messy in my attempts to keep things immediate. And his style struck a chord with me on some level. He's probably the only artist in watercolours I've thought that actually does what I've been trying to achieve. Rhythmic patterns and shapes, often dark with intense colours. Here are some of his paintings...and a link to a website with more of John Pipers work here.
