Aker Brygge lighthouse, lonely man and an invisible dog

This was a sketch from very early one morning before the quayside became busy with people, it's a popular spot for tourists and is just beside where the local ferry stops to drop off the passengers. There was only one chap wandering about and he was looking out over the water, he had a dog with him at the time but it was scooting around in the background and a nippy little fellow. A bit too quick for me to capture on paper. You can see the dog in the photo though, I think it he after the seagulls...
