Fill The Frame
This is a common problem for new photographers. They don't "Fill The Frame."
Get close either physically (zoom with your feet), or through your choice of lens, so that your viewers can see the important details of your subject.
Don't drown your subject in a sea of background.
Robert Capa famously said, "If your photographs are not good enough, you are not close enough."
