Greetings, I had a couple questions for you about this pack; if you could answer, I'd appreciate it.
1) Are your original textures 64x64 source files, or do you have the capability of rendering some at 128x128 or 256x256, etc?
2) Have you ever considered releasing normal maps and perhaps specular and parallax maps for these as well? This would add enormously when running Optifine with normal maps enabled, and even more if it also had specular and parallax capability for the Continuum shader.
By the way, although I personally am overriding some of these textures with those from other texture packs (I really need 128 or 256 for most common blocks), I have to say that this pack by and far has more character than just about any other pack out there.
