UPDATES:
All blocks are displayed in my demo map you can download under Downloads.
For Medievalism I recommend using a shader with POM support. My personal preference is currently SEUS HRR 2.1. Some textures like glass look much better in SEUS PTGI and the image is sharper but it does not support POM which greatly enhances the textures.
INSTALLATION
Installation is straight and forward, you only need Optifine to run it and your desired shader.
After that just drop the downloaded resource pack(s) to the Minecraft resource pack folder:
.minecraft\resourcepacks
I'd also recommend allocating a bit more RAM to your game instance in the Minecraft launcher.
