Nature and Travel Photographer, sometimes also some work with Models. Usually based in Germany but i enjoy travelling, so you may find imaging from several corners of the world. I love to work with DT, its a great site!
I would say People photos may sell better, on the other side you have a hard competition if you have very common subjects (businessman with phone, newspaper, etc) If you have people fotos and hardly covered areas, your chances to have a top seller are good.
I remember my first commercial people shooting, I created a variety of common themes (young girl smiling, springing etc) but the "top seller" was one pic where the model had head aches.
