Hello!
I've watched the videos.
And think that they need more work with selecting the better shots, stabilizing, slowing down where it's possible, working on timing, and editing the footages to clear unwanted objects, blur backgrounds/foregrounds to focus on main objects, sometimes., chose more shots with faces rather than the environment, put less distracting music, but nice modern tunes certainly, create another text animation, maybe use a transitions between footages, etc. There can be a really lot of work.
