I'm afraid that's as good as it's going to get Cupressus don't like their sides being trimmed more than a fraction.
I can see why you wanted its width reduced - it's taking up a lot of your garden.
What about getting rid of them and having a tall trellis fence and covering it with evergreen clematis and some roses or something like that? You'd get the privacy without it using almost all of your garden.
