Here are some easy props that you could use to make your photos look much more unique.
Have your subject look into a mirror and get behind them to take a photo. Make sure to have good lighting. These photos all used natural light. Using a mirror in different ways to create a reflection is always a cool way to add something to a photo.
By using something like a doily or a scrap of lace you can cast shadows on the subjects face. You will need direct light on the subject if you want it to really contrast against their face.
With a CD, you can cast rainbows on someones face, or you could use it to capture reflection. Here my subject just held the CD to their face and I got behind them.
By holding your phone right under your lense, you can capture reflection shots of your subject. Here I held it directly underneath the lense and then I tilted it to try and get different angles.
In the first photo I used a leaf to blur the focus of my subject. This added a cool lens flare look to the photo. In the second photo I used my fingers to frame the subjects face.
