I really liked the graphics and the color treatment on the animated sections. They were really rewarding visually, so I could not help to feel let down by the sections on white, where I felt that there could have been more... better camera moves, a faster paced cut, a more animated mix of the band members, maybe some more animated elements to connected with the rest of the clip- that's why I gave it 4 cows.
The opening silhouette postcards - what is that? Mr. Mercury? Good stuff - a little long - consider a radio version of this song with one less "interlude" - "bridge" - nice color effect on the performance sections with the percusson players faded in the background - Rock on!
