Some of the nicest shots I've seen on the forum but the purpose of this forum is to help so here goes.
Three comments:
Many of the scenes are too short to adsorb before flipping to a new scene making it hard to watch. Try to extend most scenes to least 10 seconds.
Many transitions are too abrupt. If you replaced 50% of the transitions with scene to scene fades it would be much easer on the eyes and the senses.
Your video length of 4-5 minutes is great. Videos approaching 10 minutes bore most audiences no matter how good the subject.
A little re-editing and you'll have one of the best videos posted here.
