OK, one last thing about the GO3 poster. The wings.
Aziraphale and Crowley's wings were modelled after swan wings, this much has been confirmed. And it was done meticulously. Here's an actual swan wing vs Crowley's wing from S2:
The numbered feathers are the primary flight feathers. The ones birds need to be able to fly. The ones that get pruned to prevent birds from flying - aka, to ground them.
Yes. So.
On the GO3 poster, neither Crowley nor Aziraphale has those flight feathers. At least not as long as they should be.
This is Crowley's wing from the GO3 poster (mirror-reversed, just to have all the wings in the same direction) vs how it should look with normal proportions:
This might be just for composition, sure.
Or it could be a metaphor - S3 Aziraphale and Crowley are both missing their primary flight feathers, they have both been grounded, tamed... not allowed to fly away together to Alpha Centauri.
Shout-out to my friend Sophie, who noticed this first, edited the pictures above, and gave me permission to share them here.
