I have plenty of ideas but my favorite is something that captures something about the person I'm shooting. Do you have a hobby? 50 cats? A lama? Taxidermy collection? Beautiful people doing strange things are my favorite. Its really much more madness then method.
I have also done a fair bit of modeling myself. I know the pros & cons and will try to make it a fun and comfortable experience for you. I love shooting outdoors in beautiful natural settings as well as sneaking into abandoned buildings and other places that I probably shouldn't be. Always looking for new settings and usually don't shoot in the same place twice.
