The free standing ones are the easiest cause you can just walk around them starting at the bottom and work around and opposite to peeling an apple. Those ones against the wall and over the hedge would be extremely difficult, especially the first time, I reckon you've done a great job, the effect is there the client will be happy! You'll develop an eye for each of them and will be waiving the hedger around most of them without a second thought in no time, and get the pruners out for the bits against the walls etc. Good work I say, who wouldn't want a garden that looks like that.
