I can't say I know much about the use of nunchaku, nor the way you're using it, so I can't really say too much, but I do have a question or two.
Do you have any training in using this weapon, (If so, what school/lineage?), or is this a 'freestyle' performance?
In that case, I'm not sure I'd really call it martial arts, more MA inspired dancing, closer to XMA. Not that that's a bad thing, but not the kind of thing I'd post to this forum
Also, to give you an idea of what I mean by trained nunchaku vs freestyle, here's a video of some impressive nunchaku work by Nakamoto Masahiro, who I believe is a 10th dan in his system.
Not really sure about the validity of this video, just found it on youtube, but it looks solid to be. Any Karateka who would like to correct me, or provide better examples, please do
