This particular slide show is, for my taste, too hectic and fast paced especially with the choice of background music. Watching it makes me feel restless and I cannot enjoy the beautiful pictures. The music fits the choice of pictures but the slide show effects would rather go along with some sort of Hip Hop MTV Music style.
I know that you might have just played with all the available effects of Animoto but still... it doesn't help the pictures, it doesn't emphasize or support them, because the effects are too prominent and distracting.
