hate to be rude but take a look at Tim Lane's wax up where the wax meets the tooth, no ridge line. Where the gums meets the teeth should be smoother, you make a ledge, this is not a natural look. Try smoothing the ledge down a bit. A little less sharp triangle on the festooning, but you improved on not taking the festooning all the way to the sulcus. Progress, keep a thick skin and keep trying.
