Not bad for a first try

The sprites were well done, and the animation was decent, but the lip flap needs some work.

In fact, while the story is interesting and a natural fit for the Sonic world, the dialogue seems so lifeless. Try and make it more natural. Also, it would help if you tailored the lines to the characters. Give them different fonts or colors or something.

Also, regarding your new character Sparkster, be careful not to make him too important to the plot. He should be important, but an original character should not overpower the existing characters. In fanfiction, we call that a "Mary Sue" character. Look it up.

Gewd Movie

I liked the bit where tails had a sowrd to his head. It gave me an errection.

not bad at all

great for using sprites, looking forward to sequel

Not bad for a first flash...

Although I could see that some sections of the movie could have been a bit smoother, this was a pretty good try for a first flash.

Keep up the good work!

Not bad for a first time, needs improvement

Decent effort, really. However, you still need to improve your graphics... at times, especially in the beginning, they were way blockier than they should have been, considering the source material. Also, the window for the dialogue looks out of place with the background, maybe blend it in or put the dialogue on the bottom of the screen or something?
