This is the frist of a series of videos that i filmed in the Douro wine region.

Very nice. You picked a great time to shoot. Just a bit of color in the sky and the overcast helped to keep things from blowing out. Thanks for a great share.

It kept my interest, even with the long scenes, so very good.  There were 2 points where something happened with the camera movement (1m23s, 1m55s).  I would cut these out/change scene here.  As a viewer I was lost the video, enjoying the smooth journey, wondering what the structure was all about and where this wonderful location was, the anomalies in camera movement snapped me out of this trail of thought and distracted me.  Also for me I feel it was a little too dark/underexposed.  Overall I enjoyed watching it and look forward to seeing more.  I hope my CC helps, I could of just said all was brilliant, however I don't feel that helps anyone.  These are my views, you may not share them or they may not fit into your style of photography, that is cool.  Thanks for sharing.

Thanks for posting, very scenic
