I wouldn't seek an advanced way of becoming lucid, if you already have found a way that works good for you.
The next steps lie in the dream space, dream manipulation, manifestation, seeking knowledge about yourself, communicating with the unconscious, healing yourself and others from the dream state. These things take years to achieve, and years upon years to truly understand.
Start simple, by doing things you can't do in waking life, or practise a sport or skill. Do things you find interesting and funny, to train yourself to understand your dreams and desires. Eventually you will begin to see things in a different way and moving on to more complex ideas and actions.
