Lots of potential in those landscapes David, Don't take this the wrong way but unfortunately I think they lack a little something! Good time-lapse photography almost tells a story of the location with things unfolding in front of your eyes and then disappearing again towards the end. I was so hoping the tide was going to come in and flood the river bed and then retreat again towards the end but unfortunately all that happened was the clouds moved. Don't get me wrong I couldn't do any better and my hat goes off to you for the time and dedication you need for these things but I just feel that something needs to happen or you may a well just take a single good photo.. Sorry
