Yeah Mark; this model had no problem with body control just had difficulty relaxing her face, she's a dancer, and I think she has great lines, feet and hands. So I will use her again - just have to practice a little.
Anyway, not to worry about copying - we are all copying - there is very little that people like Schatz or Holloway have not done. I think it takes years, first to get one's technique and quality to the level of people like Schatz, and then to keep experimenting and develop our own style that stands out. Anyone who thinks otherwise is kidding themselves in my opinion. We are all just shooting within the confines of a 'studio' underwater.
I've been shooting through chiffons for a while, I love the effect. In fact I think I posted some on WP here a couple of years ago.
Much of what I do with chiffons involves nudity that I don't post on WP for obvious reasons. I think for the most part chiffons don't work very well with clothes unless they completely obscure the clothing or involve things like portraits similar to the one I posted.
