Hi,
I am a certifided judge and there are a few things that you must consider. is that we as judges only get about 10 seconds to look at each couple on the floor depending on how many couples there are in the heats. As far as the lady instructor goes that is not and I repeat is not the case. You are being judged from the moment you take your first step onto the dance floor until the time you leave the dance floor. I have seen so many dancers worry about what other people are doing that they loose their concentration thus they mess up what they are doing. Try to remember 3 letters and they are C. C. D. Confidence, Control and Determination. You must have Confidence in yourself and your teacher. Control is something that you learn. Determination is just being determined to do the best that you can do. Also we as judges start by looking at what is most offensive to our eyes, and as you know everybody is different including us judges, and then we go from there. I hope this helps. Keep on Dancing.
