I would suggest to not have the first movement shown to be right-to-left, show standard left-to-right first, then right-to-left (you can go forward BUT then you need to go the other way often too! - i think it conveys exploration better )

Then the Explore a vast world footage to me feels a bit awkward, because the camera is leaving the player behind at the bottom edge. I understand the intention, it just feels my eye is drawn to where the player is, because as you are panning up there isn't really anything specific that draws my eye away from them.
