Photography is a unique statement made by one self to the world. In this instance of people photography, the photographer makes the cast works for him. Cast like the hair-makeup stylist, wardrobe stylist. As a photographer, you gotta tell them what you expect in your shoot, rather then leaving them to do what they want and you capture the aftermath. You're no better than a camera operator, compared to that a thinking photographer.
Shooting people ain't about tits and butts. If that's your aim, then the whole issue of you shooting people will have to go through serious analysis. Having gone through some of the images snapped by you guys, I seriously dun think much of those who basically shoot just babes, tits & butts.
What's really crucial is that, you know what you want in your portfolio. Stick to your ideas and concepts and your own style appeal, than having others to arrange your shoots. I find outings a waste of time, simply because there's so many photographers, so many opinions that one will find it hard not to follow. Think adversely, see what others can't... What one will need is a strong foundation of technical knowledge to start, a good photographer is one who leads, and not being led on.
