Portrait style photography is some of the hardest to master and you really need to know your camera and lighting techniques to become good at it. Whether you shoot it or not, studying it will make you a better photographer.
I could post stuff up all day long because it's really how we make our money with photography. No one wants to buy any of our landscape stuff because these days, everyone thinks they're a professional landscape photographer, but I'll still have landscape photographers who are pretty good call to ask about doing some portrait shots of their family because they cant seem to figure that out.
