Great job on this David. I know it can be a challenge to find free high quality video..I just completed a film trailer using free video and it took some time even to find simple things I liked that were free or royalty free.
I seem to be hearing just a small amount more volume in my right monitor. Maybe it's my setup here...not sure.
I think both music and video are good....the music seems faster, and the video seems to be moving slower, even though the frames are likely synced to music changes. IOW if she were moving a bit faster instead of in slow motion it might add more dynamics to the whole....just a thought.
