This is the first of what will be a series of suggestions regarding the flora of Middle-Earth.
At the moment, date palms have a foliage texture which does not fit their appearance in real life, giving them the look of a broadleaf tree instead of a palm. Attached below are the new leaf textures, which give it a more accurate representation of its real life counterpart.
In addition, the nature of the wood is a little different, and has a rougher texture.
The structure has also been reworked, to better match the spherical crown of real life date palms, as shown in the iso rendering below.
The layers of the crown of the tree are shown below, starting from the bottom (top image) and going up. Note that, for increased harvest due to a larger tree, four dates are also attached to the wood on layer 2.
That's it for now! More suggestions regarding the flora of Middle-Earth will be making an appearance soon!
Tbh this suggestion was more focused on the shape than the harvest. I suppose there is room for another 4 nuts on the trunk. I'll be doing some more similar suggestions later; I figured that while Ithilion is busy being the wiki's lore Nazi, I'll be the biological accuracy Nazi ;)
I hope that you'll cover some of the issues on the textures of certain woods- including how for some reason the planks are different than the base wood color of the trees on almost all of the new wood types
I don't really agree with the "disheveled tree". Eregion is actually nicer than the Lone-lands the Fellowship had crossed before and Gandalf says: "There is a wholesome air about Hollin. Much evil must befall a country before it wholly forgets the Elves, if once they dwelt there."
