Man, I remember doing those. Sheesh. Didn't like it, not my style, so I only did about 10 sessions or so (back when I needed the money for gear).
My recommendation to you is to collect your favorite Senior pix and duplicate the poses putting your own spin on them.
Here's a few I did of my daughter, and some of Jordyn.
