Contructive criticism
It's obvious to me you have a lot of artistic skill. The characters all look good and you're also pretty good at using flash. This flash is good quality and well thought out. Keep that in mind when you read the following criticism.
I thought there were many weak points to this flash. For one, the backgrounds were very plain and had no depth at all. Try using gradients next time, Or make the backgrounds in Photoshop or something. The animation ranged from great (the van driving down the street) to bad (when he did that odd flip move and killed everyone in the corridor). I would say one thing you need to work on is camera moves. They were basically non existent. When the character is talking, having the camera pan around them or past them. This could also improve the combat, if there were different shots (such as close-ups, motion blur, panning, etc.). Finally, I can't really say much on the storyline because I don't have the patience to watch the first two, but it seems a little weak. Maybe its just because I can't follow it... well anyways, good job and I hope to see you use some of these suggestions in the next episode.
