Lines and shadows

I was down at the marina with Blipmate looking for whitefaced herons building nests but couldn't find them. Lots of other things to take of course. The tide was low so the boats sitting on the mud. This one caught my eye with its lines and shadows.
We did get to see where the herons were flying into but you can't see the nests. Lots of shags feeding and people in boats going fishing or coming back. Sometimes they seemed to clash but not really.
