Maybe paint the space a darker gray than the rest of the house. Or add a window over the double door. I would add a row of windows to the garage doors.

I would get a landscaper to design a plan that draws the eyes away from the garages toward the other part of the home. Right now, the garages hold the most interest, and you want to change that.

I think both jck910 and Sammie J have excellent points. For some reason the gable above your garage and your other front facing gable look unfinished to me.

Consider a modification of the roof line like the one below on the front facing gable where you have the finished roof line and the window. A window that would coordinate with your other windows. Just posting the insp pic below for concept of the window and roofline modifications. I'm not a designer or architect, just going by what I would do. Hopefully you get other input.

I'd consider a color change. The white trim draws the eye up -- like white arrows. Not suggesting this color, just grabbed something from the brick.
