I will try to give a feedback like Jm did, but sorry for my poor english

Speed:
Speed is far to be the most important. Each advenced chucker has already a good speed and we can't compare easily this point on a video.
Passes, Aerials, Digit moves :
It isn't because a guy do a lot of passes or another do a lot of aerials or digits moves that i will vote for him. Each person has his own style; some style have a lot of aerials, others have a lot of passes. The moves isn't the most important, but it's how he is good in his style.
Wide variety of different moves:
I think it's important! repetitive moves during 3min is boring. to catch the attention of a person, you need to do differents combos, show him what you can do.
Technical:
showing skill ? i'm not sure to understand, but it's why we do a video; to show our skill.
Camera angle or edit skills:
I think it's important too during the world cup unlike to the chuck off, but it's far to be the most important. I think you need to find a balance between editing and showing your nunchaku skill; between non-edited and over-edited. Coll camera angles can give some really cool effect too and i think it's important to change view instead of having only one point of view.
Moving feet, stance switches:
For my part, it's really important! i like to see someone who isn't concentrated only on the nunchaku but also on his body moves. That's why i'm a big fan of chinese style; precision of the body movements. Of course, i don't vote only on this point.
Standing in one spot:
I f i see someone who have a cool footwork and someone who is standing in one spot, i will vote for the one who have a cool footwork. If one day, you need to do a demonstration; you need to move on the scene, use the space.
The music:
I like to see an editing which is based on the music; like a movie trailer. But music only is a choice; my vote don't depends of this.
Doubles :
For my part, i think it's a "little" important but i will don't vote for a guy just because he did doubles if another did a better job with singles only.
Fire, Glow :
It depends on the performance. but it's far to be the most important to me.
Breaking footage:
It means "adding strikes" in your freestyle ? i like to see some strikes well executed in a freestyle, but it's not very important for my part.
If it means "accuracy"; it's important to me.
How attractive the person:
doesn't matter. (if i have understand what it means :/)
The landscape:
Like camera angles, it's not the most important, but it's cool

The popularity of the person:
useless. it's unfair to vote for a person you like or who is popular on this forum... don't vote for the person, vote for his video.
