Thanks for the encouragement RichxFlows. :)
Birdage, thanks for all the advice. That's really clarified a lot of points that tommy brought up. The thing about isolation being the foundation of these illusiory moves is something I should have known because I pretty much learnt that in the popping classes. I was taught that a wave is really a series of pops. e.g. pop your fingers, then your wrist, then your elbow, shoulder etc. Then smooth it out if you want it to look more fluid. That's pretty much how I got my bodywave, and it's probably one of the things I can do better than others. However, I haven't really applied this concept to everything I'm practicing.
It's really hard to know how to apply that to handflow techniques. Having said that, the main reason I'm trying to learn handflow is that I thought it would be a good fluid motion to build other techniques from. I don't really want to do a style thats primarily handflow. Don't get me wrong, I think there's some really awesome dancers who can make handflow look really trippy and put a lot of variations into it, but it's not something I want to focus on too much in the long term, but instead use it as another weapon in my arsenal.
Yeah, I saw Tiger's video on the main page of floasis. Pretty much blew me away. I'm gonna watch that roboting video and practice until I start getting it. At the same time, I'll start focusing on the isolation aspect in everything else that I'm practicing. I also just realised that's the reason my finger wave (when I actually pulled it off) looked good. I guess it's impossible NOT to isolate a finger wave like that, so once you get your fingers to do what they're told, it starts looking good straight away.
You guys have given me so much practical advice that I can actually use to start working on improving. Very much appreciate it.
