How did you upload so many replays in 1 post? I thought the limit was 5, anyway your replays were all cool but you need to improve in speed like ownage said. It's too bad 'cause you have some pretty nice dismemberments...also try some no grab madmans, they look cool and they're good training.
The "takori: 9 part split 1" was my favourite, even if too symetrical at the start, it was the fastest and very original, it could have used a cool ending pose though.
Anyway, look at this, it's an edit of something I did some pages ago, it could gelp you with the no-grab part and the speed which is easier to achieve when you master sambo gravity. Also, there is a standing ending pose and a boom hit (try those too).
