I found 13 mistakes 1. The intro is blended in with the A animation. 0:00 2. The circle in the B animation is not supposed to disappear, since it's supposed to form a B with the other circle and bar. 0:18 3. The 2 ends of the C are supposed to pull apart more. 0:22 4. C is rotated the wrong way. 0:27 5. C is rotated the wrong way. 0:28 6. C is rotated the wrong way. 0:38 7. The D animation should be longer. 0:50 8. The guy in the I animation is showing the number 6, when it's supposed to show the letter I. 2:00 9. There is no W animation. 5:02 10. The Y animation is not supposed to freeze. 5:30 11. The 4 is supposed to stay on for 2 seconds after the lines disappear in the 4 animation. 6:49 12. The 5 animation is completely messed up. 6:52 13. The 7 animation is supposed to zoom out for 3 seconds and then zoom back in. 7:21 Other than those mistakes, I would say that this video deserves a like. Thanks, Jason!
