I've gotten all the rings (including the bonus one), all the achievements and the title. The "Scrambled Eggs" quest is complete, yet I only have the basic easter mugshot on my Lodestone profile, not the shiny one with the blue background. Am I still missing something?

Apparently it has something to do with the hatching basket or talking to the NPC who gave you the secret ring again, or something... I just went in-game, tried to talk to a number of npcs, tried to place more odd eggs inside the basket, and apparently now it's good
There is typically a delay between the time you complete seasonal events and the time the background applies to your Lodestone. Perhaps it just needed time?
