First, nicely done. I especially like the squares (books?) floating. The men with the concertinas or small accordions are also nice. Something about the movement there. Your transitions are all the same, try a fade or other technique to take us from scene to scene. Also try to make sure video tells a short story. Seems like you visited several countries or areas and spliced them together. Watch your continuity. Camera steadiness is crucial unless you are shooting to purposely simulate a hand held effect. Watch your focus. Most dslrs do not have follow focus like regular video cameras do. The black bars at the side of your videos can be removed if you set your video editing program to match you frame size. I like the higher angles mixed with street level views. Just don't take us too often back and forth or we'll get seasick. :) I don't how "pearly" these words are, but you've got a good eye. A good book that isn't very expensive: http://www.amazon.com/Shoot-Video-That-Doesnt-Suck/dp/0761163239
One like from me :) nice try, keep working. I dream that some day DT will accept video footage... :)
No, transitions are not good at all. Please forget about transitions, this is my "pearls of wisdom" for you. I worked in video editing many years, trust me. Using transitions is a way to cover jumps and label you as "amateur" (a jump cut occurs when you have two consecutive shots with the exact same camera set up, but a difference in the subject).
Seawatch1 advices are good, follow him.
