Mewing can help to make the palate broader, but it wont significantly Change your facial structure unless you're still in puberty (Although even then the changes will be most likely subtile)
The only Thing which can potentially make your face broader/more defined is chewing
NOT normal gum chewing, since you want to develop thick fast twitch muscles in your jaw you Need to chew tough Things
The Problem on this site that there's a lot of Bro science going on here
Like People are Posting Pictures of their faces from a 1-2 year Progress, and they think that their face has become more symmetrical and defined while in reality it is just the different angle/Lightning or Bodyfat which creates the Illusion of a changed bonestructure
I think that mewing along with a good posture can be great for your Health, but dont expect that your face will significantly more beautiful
This only leads to unecessesary Frustration since the Progress of mewing takes a VERY LONG time
By the way here are some before and after pics, in the last pic im pulling my loose tissue and facial fat up to reveal the changes of my jaw https://imgur.com/a/K7cPA7M
Have your jaws swung upwards at all? From where I'm starting, having such broad, defined masseters along with the rest of my face being retruded would look weird. Not that I don't currently look bad anyway, but you probably know what I mean. I recently bought one of those sensory chew toys after seeing that thread here about the guy with autism, it definitely seems like a good thing to use.

Sorry but this post also reads like bro science. You are basically making a claim that you are not backing up.
As for the progress pictures people are posting, yes I agree allot of it is just different light and angles.
