Need feedback about videohive projects.

Hi guys. I need your help. Hard rejected slideshow. Watch here
What do you think?

The video is lagging for some reason. Not all of the transitions are smooth. All of the scenes are same. The camera movement is the same all the time. Try to add some spinning motion with the camera and show the pictures from different angles so you diversify the video.

Thanks for the answer.
What do you mean, "The video is lagging for some reason".

I can notice the movement of the particles is not smooth. It’s like they’ve been shot at 15 fps as stock footage and then exported at 30 or 25 fps in your video.

Everything is clear. Thanks for the comments.
