Depends on what it's for. Fun project.... just go by whatever my mind thinks up and I don't plan or worry about what goes where. More serious work, like promo renders, I look at what is the important thing I want to show and then visualise what would work with that thing and how the scene will look like. Then in my mind I picture the whole scene and go through light settings and camera angles. Once it's perfect in my mind I work it out in Poser.

 

For larger projects, like comics, I draw rough sketches of the scenes, make a storyboard. What goes where, what's the cam angle and so on, it's all on paper. Once the storyboard is done, work starts in Poser.
