These are really good replays for a beginner.
Fair warning: The no-lifers and old-schoolers are only impressed by more "limp" replays. I mean limp as in hitting the c key to relax all a lot. That way, the hits will be more speedy and hard-hitting.
It's rather about fluidity and smoothness. You can achieve that without relax too if you know how. Relaxing is one of the easier ways but there are actually some replay makers who are too relaxed. You just have to figure out what has to be used when. Using hold is hot. Just make it look like your whole body is contributing to your move.
