Neck Hurts - This replay had nothing to do with your skill level, it was simple an awful opponent who made no effort to counter your attack, I mean for got sake he broke his own neck.
Tip toe - It was obvious you were going for some kind of DM here which I don't like, again your opponent just doesn't seem to know what he's doing. It was an easy save and I guarantee any members of TA would counter it.
Slam Down - Again just someone who is unable to counter any attacks, they person you were fighting could have easily countered that and suplexed you or something similar but he didn't even try which suggests again he's new to Aikido.
Try again with skilled players, submit more replays but for now it's a strong no.
