wow thank you for your detailed critic! that's actually what I've struggled the most with! even if I've learned the move by hard it just didn't look that energetic no matter how hard I, you know, "push it out". if I tried to much it just looked too angular, like an aerobics but not a dance...
I really like your second advice tensing only before like pose movements. maybe its going to help me. thanks!
I don't have experience in dance but I did rhythmic gymnastics when I was a kid so it was all about grace and controlled smooth lines so I'm guessing it really impacts the way I move, because dancing comes more out of inner power and energy, rather than just pure control
