imo, the first one isnt a very good promotional video.
too many pieces that are too short, and are all over the place.
plus the video is just too long.
something like 1 min long with 3-4 pieces enough already.

Bagus sekali...

Sum suggestions:

Let pieces segue into the next, not abrupt stop-starts.

Arrange the pieces so they segue in a circle of fifths progression, will sound so seamless as the ending chord resolute into the starting chord of the next piece. Transpose if necessary.

Arrange in ascending or descending tempo.
