Hmm... in the spirit of constructive criticism, it looks weird how it closes and opens her eye at different speeds. I think it could use one more frame when it opens, or one less when it closes. And perhaps a teeny bit more time closed.
Then again, it IS Pinkie Pie, guess all my arguments are invalid, lol.
ooh yeah , now i got it why its happened!! i had 2 key frame for closing, but only have one for opening XDD thank you so much for mention!! now i learn something moree it is just my second animated job
