Hi, well as you can see, everyone's different!. I do back, one side, front, other side. I then go lightly over the feet, then the hands.
Then I finish by going lightly over the whole of the back, then the whole of the front.
I think the main hints I could give are:-
Whatever you do, do exactly the same each time, so you don't forget anything.
If possible, have a large mirror that the client can see when you're done, then if they say they want to go darker, you can go over them once more lightly (or say, just lower legs) - makes sure they are happy
Kneel down to do the bottom half of the body
Do the hands and feet separately and really lightly
Good luck
