good animation, bad characters
Your animation quality was quite good, but sadly it is the only thing that makes you flash worth watching.
My biggest problem is that the characters are super cliché, I've seen them a million times before, and I just tired of them. I'm shur their is a lot to your characters I don't know that would make them unique, BUT it wasn't shown here so I instantly don't care about ether one of them.
Also on a technical side, why 18 FPS? it seems like a really odd (and low) amount to use for a fighting animation. your movement would have flowed a lot better if you just bumped it up to a standard setting. 24FPS is a standard movie speed, while 30 FPS is stuff like TV, there is a really important reason we use these numbers, so unless 18FPS was important reason, I say stick to the norm.
Overall good job, no matter how much I bicker, its not like I have anything better than this out right now, so really good job.
