On the pacing issues, I think so much of that depends on the viewer's desire to watch johnny depp. The pacing is a tad uneven here and there, but I bet that was because your source video was different lengths.
All videos are meant for a particular audience. Johnny depp fans won't find it slow or boring at all, but if one does not give a hoot-tootie about mr. depp, then chances are high they will not want to watch the video....but that is ok. a video can not be all things to all people. so my statement is not really a criticism but more of an acknowledgement that different things appeal to different people.
Here is a better explination of what I meant by changes:
At :31 you are on a b&w shot that slowly zooms into his face. The qualities of the B&W changes in the middle of the shot. That was probably how the original shot was.
I also noticed flash frames at these points: :51, 1:43, 2:08, 2:18, 2:50. A flash frame is where you have 1-3 frames of a shot in a sequence of otherwise more normal length shots.
All in all, this is very good for a beginner. Please do not get discouraged. I know my first videos were so bad my teacher laughed at me. Now, 30 years later, I can tell you that some of myvideos STILL suck! but I always have fun.
