You can try moving the 36" octa in real close and using a fill light or reflector in tight as well. I don't like flat lighting, even in situations like this, but I will go for less of a contrast ratio (like 2:1). I experiment with exactly this sort of thing quite a bit because my wife and her friends are that age where they are not yet comfortable with the idea of earning those wrinkles and prefer to mask them as best they can. I'll ask my wife to pose for me after a long day of work and without applying fresh makeup, just to see what I can do with lighting for the most flattering light possible. You may laugh, but in my last experiment, I used the 74" octabank as my key light and 60" octa for fill! It was actually not as flattering as I had hoped, and I'd show the results, but then I'd have to sleep with one eye open for the rest of my life. Next I'm going to try the 39" DO on a boom with deflector disc and two layers of diffusion with the Lastolite Triflectors to see if that's more flattering.
