If you get a chance, post some of the video of your movement. I have been looking at the ones on youtube and they vary greatly in apparent quality. However, liu he ba fa's movement seems particularly interesting to me and I like the way it seems to combine multiple methods of power generation. It would be more apparent if I saw higher quality practitioners in action.
You're very correct in saying that the LHBF on youtube varies greatly. None of them actually match the photos of Chan Yik Yan (you can find them at www.waterboxing.com )
The thing is, we try to perform the pattern as though it's "nothing special". So it's very likely Choi was actually doing that in the video. Looking pedestrian while keeping everything internal is something we try to achieve.
I might be able to find some time to film myself after exams, but it probably wouldn't be quality practitioning.
