wuff, wuff...
even as a 3D anim, this is pretty lame. wouldn't make it on anyone's demo reel...
no sense of scene (like how and why are these two fighters attacking each other?); we start with a close up, but we need at least one wide shot to establish the characters and relative sizes; the stars in the background of the first fighter are much smaller than those of the second fighter (why?); when the first fighter 'evades' the laser bolts, it looks very artificial (need better control over your motion paths); in the last few frames, the second fighter suddenly slows down while its tail still visible in the scene (sloppy).
get to know your software better (especially spline control), and it might do you good to pick up some books on movie making (study the way the snow battle is setup in empire strikes back, for example)... it takes years to get 'ok' at this 3d stuff, you can't expect to convert mediocre 3d into flash and fool everybody.
