There are methods to make models comfortable. Some are already ready to act the part, while others need some handholding. In advance of the photo shoot, I provide models the story lines (or script) I want them to narrate. This is crucial, since with it in mind, they can act the role. The other method is to encourage them as they pose...not so much as how or where they are to stand, but reminding them of adopting certain poses following the script as in "show me how Meili wishes she had never met the gweilo"...or "show me how Hua is scared of seeing her aging lover...".
A pretty picture is not enough. It needs to be high quality and it needs to be original. For magazines, you need to consider issues such as leaving space on the image for word placement, positioning your subject off-centre so it doesn’t fall down the page join, and possibly placing the subject on the right-hand side of a landscape shot for maximum impact.
