if thats the case then you seem to have found your way of doing it. i would continue in that same way if i were you, unless of course you really want to change how you write them. but in the end it only matters if it sounds good to you, and works for you. i mean who cares if the way in which you write a melody differs from some famous players way of doing it. that is the thing about music it is one of the few truly individulistic things you can do, so it doesn't matter how other people do it as everyone approaches things in a different way.
