Your animation was smooth...
But I'm not impressed with your over all envision of how the music video was put together.
Not many people can envision a perfect slew of images when listening to music.
While many people agree your synchronization is on que with the voices. I honestly feel that the images were not strong enough for the music video.
Then again...the song wasn't all the great either.
Your animation skills are definite and excellent. But I feel your animation style is best focused on making a cartoon series.
I somehow feel you struggled trying to make this a GREAT music video...and instead turned out to be an 'okay' music video.
You make GREAT cartoons, GREAT characters, GREAT stories...
not so great music videos.
