Sometimes people want to make things too complicated as a photographer. I prefer to keep it simple.
This photo is a perfect example. One light, plain background, model and a chair. Nothing to distract away from what I wanted to be shown.
Of course you can do a fuller set too.
Even this is still pretty simple. I could have easily added a table to the background with some flowers or a vase. Even a painting on the wall. I find it very easy for those additional props to become distractions, so I prefer the simpler set.
You really need to consider does the extra prop add value to your photo. Sometime yes, but often it just becomes clutter.
In design you will often hear, remove one thing once you are done and it will get better. I think the same concept works for photography.
