IMO Starecta is the base. face pulling and expansion imo wont give you the results you want without starecta.
Starecta is the anti-base. To start from the base you'd have to actually
start from the base. Starecta argues that posture and structure is determined by the bite, while in my view it's clear that the bite you have is determined by your posture. Starecta is a top to bottom approach, starting from the most superficial dysfunction (bite) and continuing the way down towards the most primal, original dysfunction (usually hips or feet). But there's no way to guarantee you'll ever reach all the way down to the the feet, or whatever is the REAL base of your postural problems.
Working your way in ascendion from bottom to up, on the other hand, is comprehensive, because you won't be able to move on to the next link in the chain before have the former parts of the chain in full control. But you CAN accidentally miss a link when progressing in descending order.
The before-after pictures of the creator of the Starecta method do show improvements, but the final posture is still far from ideal - he needs to go further.
In contrast, this is how I stand:
Final results vs work in progress. See the relationship between the head and upper torso. Or position of head & hips. He is semi-literally sloughing compared to me. See the difference in core activation and athletic form. I don't do any sports at the moment, yet I look fit, because instead of merely opening the body, I have strengthened it and learned to actually USE it in daily movements. I'm functionally symmetrical up to somewhere around the upper chest area. When the remaining musculature above this area starts to finally work in unison with the rest of the body, the wholesome forces of the changed movement patterns will start to reshape the facial structure into a more symmetrical form. My jaw has already started hanging towards the less developed side of the maxilla, meaning that some static structural pressure is already being generated into that direction.
