Sunsets on Kettle Cove in Cape Elizabeth, Maine.
I wouldn't really categorize this image as a "driftwood" picture. Really this is just a piece of tree that happened to have fallen in the ocean. Give it a few months and as the bark gets stripped bare by the endless tides and the combination of salt and sun bakes it to grey, then it will earn the title of driftwood.
For now, here's a stick in the water.
