Absolutely awesome. Okay to add to main game? I'll probably turn the bush into a small tree. I'm thinking of shrinking one of the Aleppo pines for a custom tree prop there to represent the sacred olive tree.
Created a new work-in-progress Civ entry on the Wiki.
Better update the portraits ASAP? Especially the heroes... who was that doing the Han heroes and Cleopatra?
Before you start experimenting, back up your important data, or better yet, create a system image using Clonezilla.
From what I've seen, the PuerOS documentation is very poor, and there's no information about updating releases—you have to guess.
So either they didn't bother to write it or there's something wrong with the updates.
Or maybe I was looking in the wrong place?
In either case, be careful.
Good luck.
Regards.
