Nate's Tweaks is a texture pack which aims to improve the vanilla textures without breaking the feel, but this texture pack breaks that rule. This is kind of my all out pack, where I don't need to really care so much if the blocks are too far from the originals and focus more on what blocks would be nice to have! Obviously use this pack aware that builds will look drastically different without the pack on.
