Ever noticed any animation errors in fan animations?

Yes, of ponies

Have you seen any animation error when you see a fan animation, say like FlufflePuff tales.

This animation: http://www.youtube.com/watch?v=1haUMfNiEb0

Watch the video, and rewatch it a couple of times to catch the animation erros

Although it is a pretty neat video I will love forever, it has sooooo many errors and mistakes, no offence, for example:

Twilights mane style keeps changing, if you notice

One part, half of the eye color isnt white, but purple, well, a very small part of it

Most parts, the flying looks bad, like its just hovering

Most of the tweening is just took to far

to much tweening at some parts
