Would love to see some more customization features to the races (which one might envision in the form of clans, but ideally not just that) - I think as one big character creation update type concept, perhaps around when they're going about updating graphics in general this would make sense to be part of the milestone graphical update program. Could be quite nice (might mean getting more facial hairs, or hairs in general that don't have pixels baked right into them lol).

Au Ra, imo, would be lovely with their closer to concept art as options- the females had this cool succubus look and the males looked quite draconic.

Lalafell maybe might see a very very distant cousin moogle like race. It wouldn't be fair to count Vivi like race as a whole clan, but it could be a bonus - extra if it gets more of the shadowy vibes than just dark skin like Vivi is in FFXIV lol (think more FFIX), alternatively may also think Yukes (mammets, I've head cannon that the lalafells trapped in Sil'Dih with the onsault of zombies and no nights as they're deep within the city turned to advanced forbiden magic to transfer their souls to mammets).

But I feel this all would be better when the races are improved in general, like ensuring you can have a muscle slider (as some races don't), particularly I'd love if there was a bulk slider such that you could have slender, thick, or thicc. . options lol, or separating certain features that were combined for sake of memory (I assume) - so like seperating horns from face, or hair from face in Hroth's case.
