Hmmm let me see if I can describe it. Part of it is being too big and sharp with the styling, particularly when not called for. Feet that are too fast. Too much hip motion. Being disconnected from the music and your partner. Dancing on top of the floor instead of being grounded. On top of the beat instead of having that laid back, silky feel like you have all day to get from 1 to 2. In general, too flamboyant. When you watch WCS dancers you think have no style, look a little more closely. Look at how connected they are to each other and the music. When they do some kind of styling, it's very purposeful and with the music and their motion, not just sticking their arm out because it's free. Watch some youtube videos of invitational winners, and you'll get some very good examples of what you should do! However, the best way to dance better and in the right style is to take lessons from a good WCS teacher.
