Make sure the background you choose complements the subject of the photo. If you take a photo of a model against a busy background, the viewer's attention is going to be drawn to the background rather than the clothes. As a general rule, simple backgrounds with colors that contrast with those of the subject are ideal.
Took a look at my new Nikon 3300 camera. I also bought the RODE Video Mic GO for my DSLR. You can add me to Twitter: @JoseVBeta.
