Just saw the videos, and I have two suggestions:
1) the FAIL in your video was genius. I authorize you to put that on my suicides, it made me lol.
2) I think that since you are able to put text in a battle, you should put the names of the fighters over their characters at the beginning when both are using the same character. For example, when GC fought JR they were both using Captain Falcon and it gets confusing since P1 and P2 don't really say anything. So during the "3,2,1...GO!" you could clarify who's who and then remove the text.
