This is not too bad
This was actually notbad at all for sprites and a huge file size. the size should be worked on somewhat though, and the "BUTTONS" should probably be removed, anyways decent animation
the whole Click next button seemed to get repetitive so i suggest you remove the buttons and just allow it to play as a movie instead it will have a much better result, the click next button just tends to anoy people when all they want to do is watch a movie. And I would suggest some file Compression as it seemed to take awhile to load up. and in the end it will generally attract more viewers to your work.
