I may be meaningless, it may just be a bait-and-switch meant to illicit theories to promote the movie but if a random clickbait Hollywood Youtube channel can do it so can I.
Every single character and ship are facing towards the front of the poster with one character facing sideways but looking forwards, perhaps a sign of hesitation and Ben facing towards his allies rather than having his back towards them as all the other character.
It may be just a stylistic choice but I thought it was mildly interesting enough to make a post about it. Carry on.
