I would remove the shutters which are too small for the windows. Keep in mind each shutter should be half the width of the window. Your larger, double window is just too large. I think the windows would be nice with just the wide, white trim. You could add window boxes to one or both windows which would work especially well with your house. They can look great when filled with colorful, trailing blooms.

The door might look nice in a dark gray/blue that coordinates with the siding color. Or...you could just leave it white. Whatever color you decide, I would also use for the storm door. Some might suggest a red door, but it should be a cool red. You could fill the window boxes with red blooms, too. Plant boxwood or other shrub below to fill in the space all across and below the windows...or window boxes.

It's hard to tell for sure, but maybe look at something like Ben Moore's Hale Navy for a door color.
