in most shows you will walk out as a group and as they introduce you, you hold your arm up. as for quarter turns just make sure you smile and make eye contact with the judges. on your side pose you can drop your outside arm back some if you have a small waist. On your back pose make sure you dont have a gap between your thighs. Posing and stage presence is just about as important as how you look. They keep saying they want a softer look but at most of our shows in the south,but the girls are still pretty hard. Butt creases are not a good thing.lol< Shoulders and glutes are what does it for judges. My wife placed top 5 in jr usa"s and is doing the nationals in Atlanta. shes not on here but any questions pm me.
