Some beautiful dancing. I liked all of the couples, but the couple with the woman with the white top and the couple with the woman in the green dress are very good.

For some of my students, take a look at the posture and embrace. The women are facing the men, they don't have their heads turned to the left. They have their noses over the spines, this creates better balance. They are also not leaning on the men, no contact in the stomach. Their left arms are not up and over the mans shoulder making them tilt their upper bodies, thus throwing off their balance. If they are as tall or taller than the man then they can go up and over the shoulder. But for shorter women, don't compromise your balance for some made up idea about a proper tango embrace.
