As far as I know there are two ways to step-down from many loops to few: by adding a “diamond” - a quad whose edges are diagonal to the existing edges. Or, by adding a U-turn Quad, a trapezoid whose longest side faces the low-loop direction. It is called U-turn because of what it does to future edge loops.
The U-turn takes four loops and converts to two, while the Diamond takes three and converts to one. You are trying to go from six to two, so it will take two applications of these quads. A pair of diamonds will probably be great.
I would place them closer to the eye area, though, because the edges are not doing anything for you on their journey to where they are now.
If anyone can teach me a third technique I would be very appreciative.
