Ive always considered a "Master" rider someone who can adapt to anything they want, whether its terrain, style, whatever.
That said, it sounds like your progressing just fine. If tricks are you thing, dont forget about carving and basic boardskills. If your into spins, do them friggin everywhere. over rollers, hips on the sides of groomes, through/around trees to help navigate.
Anything you can do to safely push the envelope is what I refer to as progression.
