Have you even played Final Fantasy?
The least you could have done was make the characters remotely like their actual 'in-game' personalities. And though it's probably all 'cool' and everything to have them swearing in near enough anything they say, none of those characters don't talk like that at all in the games they're from. You should probably have considered how they actually would have acted (this probably isn't really 'serious' or anything, but it can get annoying).
Though I admit that I laughed at how wrong you'd made the characters though... Especially Auron.
The animation was okay, I suppose... Better than I could do, at least.
As for the story... Was there one?
