Updated the OP with a 2K version of my terrain textures, as requested by some people.
If the 4K was too much, then I hope these will work for you!
Also, added 2K retextures for the rocks, crystals, and big grass patches from my 2K texture pack. Originally, they were in 4K, to minimize pixellation. However, I have reduced the size for those who might prefer to keep their FH folders lighter.
