wow, an impressive sonic-DBZ crossover cartoon!
while i normaly dislike and ignore sonic/DBZ fan-movies, this one was too good, and too well-animated to be ignored!
both your character drawings, and the animation were perfect.
you drew sonic, shadow, tails, eggman and every other sonic character perfectly, it looked like the real thing, and thats something important.
then, the animation speed, and the animation itself was perfect, everything was nicely animated, and it was swift, as for the battle scenes and the face expressions of the characters, it was good.
the story was OK, not a big fan of DBZ/sonic stories, but still, it was nicely animated and it kept me interested.
as for the voice acting, it was cool, and nicely used in the movie.
overall, a great sonic tribute, and a cool fan-made movie.
i would like to see more like this, you have skills.
