The photo are beautiful and the music, with it's cristal sound, suit very well to those water landscapes.
The interludes video add life and sound and enforce the nice walk.
However, as their resolution seems not as high as the images one, I would have reduced the size, as you have done for some photos, unless this is due to the output chosen for proshow gallery.
Some transitions suit very well but some other break a little the enchanted walk.
Thank you for the nice walk that make me want to visit this beautiful area
