Stop being comfortable. Get uncomfortable! This is your headshot session, right? You are paying the photographer, not the other way around. So try new things! Try random stuff since you have the ability to experiment!
I wrote an article a long time ago about practicing and taking risks. This leads to much better pictures because if you don't take risks all your pictures will look the same.
I have to stress the importance of not being camera shy also. Just go crazy during your headshot session and do whatever you can to get new looks! Here is an idea:
First try a bunch of very different looks.
Next, look at all those looks and pick out your favorite 3. Then try to nail those looks even better. Focus on those ones for the second portion of your shoot
Then if there is still time, do it again. Each time you try to focus on one look, it will get better and better results rather than doing all different looks and never trying to make the good ones better.
Good luck and let me know if you have any questions!
