I will also post the musical theme that I liked so much.

And I will also recommend:

First, be sure to download and install a mod that replaces the Ents with a model from the Beta version. They look much better and more atmospheric there.

Secondly, I recommend downloading a very good mod that introduces quite a few pleasant changes to the game. You can read about it on its page.

That's really all. Thank you all for your attention!
