breaking down this san fancam to prove that he is a really talented dancer, a thread
jumps are made without any tension in any of his body parts, he is able to switch from stronger more sharper moves to more relaxed in a second, hand movement matches the beat, adds extra leg movements to match the beat too (check his feet) + facials are strong
arm wave touches all areas (?) that are needed to make a connected and full wave (fingers, wrist, elbow, shoulder) + extra chest movement
he added an extra arm wave before he falls on his knees while also moving his torso slightly, he falls effortlessly to his knees, doesn't hunch back (it's sometimes common) in the floor movement
adds an extra "bounce", torso and leg angles are clean and well connected
body roll is very well done + coordinated, knows how to bend his knees properly to change levels, adds a head movement + torso roll in a slight second, leg angles are perfect, arms are properly extended but not overextended, arms are also rounded (?)
entire sequence looks connected + effortless, good level change, head movement looks controlled, footwork is clean + facials are strong
arm angles are good, body wave starts from the second his foot touches the ground from his knees up to his head + head throw adds a better effect to when he kneels down
small arm wave, he is doing an extra shoulder movement + it's well coordinated, knee bending is on the beat same with the shoulder movement. he switches from sharp movements to smoother more connected ones
footwork is clean, movement is controlled, smooth and effortless + adds extra torso and shoulder movements, well distributed balance to do the legwork, body wave is properly done
entire count is controlled properly, no rushing of steps or overdancing
good isolations, he adds extra torso movements + he slow raises his height level before doing the half turn (?)
this entire part is clean + he's very detailed in his arm angles, he's extremely light on his feet and it makes the entire part look lighter, he adds extra shoulder movements and the torso roll is connected
arm angle is perfectly diagonal and it's a perfect mix between controlled and relaxed, he places his leg almost perfectly in the turn and arms don't have any tension, this whole part looks extremely natural + good facials
footwork isn't underdone (?) and it's well extended, arm and leg angles are perfect + well coordinated, arm movements are clean
leg is lifted with a slow motion effect, one needs good leg control and good balance to be able to give this effect and not tumble, the leg lift connects cleanly to the next sequence + i don't even have to say anything about his facials, look at him go
footwork looks natural and relaxed but also well done, even though the arm isn't fully extended to it's limit when he raises it, it doesn't look weak or bad, it still looks well done without that much energy that he'll add in the next arm movement
look at how he's able to change his energy and power levels throughout this to add a slow-motion effect on some parts, you need good body control for this and also good channeling of energy to not keep the same "vibe" throughout the entire part
in conclusion, please stop talking about his dancing when you're not a dancer, you're doing nothing by trying to prove that he's a bad dancer when he isn't one and you're embarrassing yourself
