Oh! Something I took a part in on HN. That's a first. Almost everything there was practical. Highly recommend checking out all of Max's work, beaming with creativity.
So its not mentioned on the post but is this your actual passport photo that was accepted and used and you have it on your physical passport right now?
While this may have not been done, I don't see a reason why these wouldn't have been accepted. Source: I am a certified passport photographer.
