How close are your lights to the subjects? Do you have the umbrellas attached?

You not getting enough light yet for a good shutter speed, #2 is f3.2 at 1/40 and #3 is f3.2 at 1/25. Without a faster shutter speed you will get soft focus from camera shake or subject movement or both. So, you can bring your lights closer or move the ISO up to 100 (I wouldn't go over that at this point).

What do YOU think of this exercise?

If you are doing the things David suggested make your eyes look for the change in shadows in between the wrinkles.
