Humm, for Namie being stiff, I heard about Namie said that she's a very shy person (?!), even until now,, she rarely smiles or showing expression when performing songs,, because of that she always do the poker face..
just look at picture or videos when she's not performing,, she can smile happily and laugh freely,,
And Namie rarely do exercise, she said that her only exercise is dancing routine 'before performances'.. I think that's what made her a bit 'unsmooth' (wut?!)
I really like Koda's dances,, though they're not as energetic as they used to be,, but she can dance really well and they match the song theme,, It's hard to imitate her moves ~
I really like BoA's dances too~! They're energetic and great, fun to watch.. maybe because she's still young and that'd make her performances more amusing..
As for the queen of dancing, I can't choose now because I haven't seen the other artists that mentioned in this topic,,
