Models: are these posing/modeling tips valid?

I like some of it, but not all of it. Usually your photographer will tell you what he wants and what you should do. This is a good start, but you could walk in and have your photographer say something totally different. Just walk in with confidence and BE A GOOD LISTENER!! If the photographer tells you to do something do it immediately and happily. Have a positive attitude, and never complain, they don't care about you, they just want to get the photo shoot done. Well good luck! =D
