Great job
There are a few things that you might want to work on with future flash projects.
1. Slow down the dialogue or put in a next button so people can follow at their own pace.
2. proof read your text, nothing is worse than a great flash with bad spelling.
3. Slow things down in general. Build up characters and don't rely on the original games for background on the characters. Give the characters their own personalities, and rather than trying to get everything into one flash, make it into a series.
4. zoom in during special moves and add some effects in the background during those moves.
you have a lot of talent for flash, and especially for a first timer, this is great (better than a lot of things that are out there by veteran artists). Just take a little more time and don't rush through it. Kudos to you!
