Michael Launder:

Also with lip synchs work on your ups and downs first. if you nail ups and downs and then the wides and narrows of the lips your lip synch will skyrocket in quality. after those two things you'll be really close! put your hand underneath your chin and say the words in the shot. you'll be able to count how often your chin hits your hand and that can give you your timing and number of openings that the mouth will do!

Michael O'Brien:

The timing of all of his movements is very even/ look like they're all moving at one speed. You could improve the interest by varying the motions from one action to the next.

Bryan Stone:

Arm gestures out of sync with the overall pace of the song. Otherwise is a good effort.
