For some years now I have been receiving almost daily email updates from the artist, David Randall Tipton. He works in all mediums and he's proficient in all of them. He lives and works in Portland Oregon and his works often depict the shores. I believe he used to live and work work on the California coast; Mendocino. I shouldn't try and tell you about him; you should visit his blog and see for yourself. I visited again this morning and saw that he recently had some tragedy in his life; his mother died and his studio flooded.
And while you are there, you should get on his mailing list and see his work frequently.
