Needs a LOT of work...
This could be a great series, if you make YOUR OWN BACKGROUNDS! The Death Egg background was hand-made by Short Factor, as well as a lot of the effects, such as smoke, the aura used by Macha Sonic, and the focus strip. Also, I saw no credit to him, nor do I think he gave permission. I suggest you make some more unique backgrounds, and use the effects that came on the sprite sheets, those are normally the best ones to use for the characters that use them. Also, how are Teenage Gohan and Gotenks together? Gotenks didn't appear until after Gohan started high school. Anyway, try harder, and you will do better.
