Something caught my eye while looking for something to vector.
 
I thought the crown looked familiar but realized it wasn’t the Element of Harmony (it has more fancier “curls” holding up the star, and has jewels along the tiara edge).
 
It, in fact, appears to be the same vector/object from Twilight’s coronation ceremony. Now, knowing DHX in the past, they’ve reused art, but given they had to create a whole bunch of new assets for this show, you’d think they would have created a new crown as well.
 
This would imply that Twilight’s crown is the Macguffin here in the movie and is rather powerful in of itself.
 
Of course, I also could be waaaaay overthinking this :)
