"Good Job"
Well as for animation, use of sprites, actual plot overall, this is a great series and a great flash, now, what I happen to know and what is shown in the different X and Zero related stuff, this is a bit out of the actual sequence of events, but like you said, it's your personal take on how things went down, still, I will congratulate you on not only comming up with a great story, but also with the skilful use of sprites to make this, and it's a fitting ending, the voice acting from the previous or the lack of it here doesn't really matter because it's an extra when it comes to this kind of animation.
