Since the mod uses a different resolution than the original 16x16 for its textures, I offer you to help you out with those. I will attach a mockup later when I get the chance. I understand that not everyone (including me) is an artist, but a mod's visuals play a huge role in how a mod feels.

Hello,
The textures are intended to be higher than 16x16.
Feel free to make your own resources as MC allows for you to add any textures you like.
Cheers,
Me.
