could be better
There were a few things you could improve to make it a lot better.
You could have put a menu in there, that would have also meant that it wouldn't repeat. This would improve the overall feel and quality of the flash.
You could also speed up the in-between parts ( I mean the parts that lead to the next scene, not sure what they're called). These parts just seem boring and longwinded, they just make you want to close it down and do something else. If you didn't want to do this, maybe try and make it more interesting some other way, maybe change some music, to build up into the next scene or something else. You could also add some humour into these sections.
The fight scenes are just a bit strange, You could do a few other things, maybe make the 'sabre fight more detailed or a bit longer at least.
You could also extend the story a bit, make it more in-keeping with the rest of the Star Wars story. You could do this by doing the foreword thingy, that they have in the real films. In this you could state which films it's between and why he's going for his revenge.
Other than this it is a very good little flash, keep up the good work and keep working on improvin them!
