Your TAS lacks entertainment.
-You use Ryu and Akuma, two shotos who everyone who's ever touched a Street Fighter game knows the basic special moves of. I don't go "wow" when I see tatsu's thrown around everywhere. This is also what got your other fighting game TAS rejected.
-You use very basic combos. I never saw you get above 8 hits (at least in the first three rounds, I gave up after that), excluding use of supers. I like errror1 also didn't get much of an impression that it was tool-assisted at all. It's just so basic it's boring.
-You make no attempts to be entertaining. Compared to
this TAS by errror1 which was posted earlier in this thread, you didn't use exploits to do the most super bar consuming moves right at the start, and you didn't use a joke character that makes viewers lol at half of the moves he does ("ULTRA VARIETY PRIVATE MEMORIES!!!"). In relation to the other points, it also chose two very different and non-standard characters, and most combos were >12 hits, going from the ground in the air and back and then in the air again, showing constant TAS-like pressure on the opponent, unlike your TAS which shows what pressure on an opponent is like in a real SF match.
That is why people think your fighting TASes are bad and are rejected when submitted.
