Lighting is your top priority
For me, lighting comes above everything and is the biggest impact on a great picture. Even if the background is great, if it’s facing the wrong way for the lighting, it’s a no go (unless you want to do some serious editing after and it will still never look as good). I feel natural light is the best and I take nearly all of my photos outside or by a window in order to get the perfect glow. You will need the sun to be facing you, if the sun is behind you, you will be back-lit and that's not going to help anyone!
