Do your photos create questions? In some cases this stimulates interest and in other cases is a put-off. When done well, a good photo will prompt the viewer to wonder what’s going on or what exactly are they seeing. What is that person doing? What is that thing?
But the brain is lazy. It will only work so hard to try and figure things out. If the composition and tonality of the photo are poor, the viewer is not going to keep viewing.
