The photos work well, not sure you need the watermark, I want to see the pics not have my eye drawn to the text on every shot.
You could improve this massively by having the shots change in time with the music, i.e. on the beat rather than randomly. The music should be an integral part of the movie not just an addition.
I like the way the vid ends on the last shot, or rather the subject of the last shot, clearly the video will end on the last shot
