If You Want To Make A Parody Piece ...
... come up with something original. This is obviously "Lizard Sphere X" except your file size is about 20x larger and tells the same story!
Work on your pacing. You spent too much time on the power up scene and the group reaction shots. The fight was also very ridged and lacked any real action.
When creating Flash cartoons, keep your file size in mind. This piece did not need to be 4meg.
Finally, instead of ripping off other people's projects, watch more DBZ and find something else to poke fun at - there's a lot there!
