I really like this. I've been playing around with your camera movement technique as well. I've got one I'm going to post today. It's a really interesting technique that does create some nice artistic shots at times. Thanks for sharing.
its excellent sarah .. love the colours and reflections .. would love to know your shutter speed, f-stop, iso etc to get this sort of blur during the day . :)
Now THIS is great blur. I've done motion blur at night, but haven't tried it in the day. Love the horizontal line of boats, and the bright reflection in the water.
