I had a look through the game files and found the line up of portraits to be released as part of the community event (maybe this is news to no one 
)
December: New Year themed Kronos
January: Valentine’s Day Aphrodite
February: April Fool’s Day Loki
March: Earth Day Gaia
April: Summer Ra
It would be really, really cool if they released decorative brooches that we could put on our villagers — for example, flowers, emblems, etc. They would only be visible when zooming in, but it would add a very nice touch of personalization.
Nothing for the Chinese New Year ?
No dlc one so far, prob because they are civs not all players have.
The scope of the event was originally stated that it would only cover the original four civs.
We still dont have the portraits of every god in AoM Retold both the Chinese and Japanese god icons are missing. Even Odin and Gaia profile icons are also missing yet. Besides icon I hope the devs could add maybe a custom HUD or some taunts per pantheon?
