Trying out new studio lights....

Photoflex 5' octodome camera left forward, umbrella camera right rear. White reflector camera right forward. First time using these lights, CC appreciated.

I think your lighting set-up is good. Obviously you about the reflections in #1.

from another novice in lighting:

I think they look good. Keep in mind the light angles when doing portraits of people with glasses. Like when you throw a ball at the ground, the angle at which you throw it at is the same as it bounces away. And, on those curved glasses it is probably more difficult to control.
