Nice job. B)
The song does fit the video quite well. As much as I wan't a fan of the song, I see how it fits with the video, and I won't let my dislike for the song affect my opinion of the MV in general.

:
I like how you started the video; the entrance of the Sharptooth. I also liked how you put the scenes of the downed sharptooth and Littlefoot's mother together, showing their connection.
Overall, it was a nice mix of Sharptooth and Littlefoot, and it shows their 'relationship' in an interesting light. Well-done.
