I knew that adding a features list might bite me in the butt. I've since edited to try and clarify that point a bit. This is definitely not a 100% faithful to vanilla pack. It's more faithful to the design of vanilla blocks unlike many texture packs with a very strong theme or setting. This means no major substitutions to the intent behind what the blocks are supposed to be or represent. Color design in my pack is a slightly different story. For the most part I try not to deviate from vanilla's basic hues, and relative shade differences I try to preserve when possible. However, the original reason I made the pack was because the vanilla textures were too bright and harsh on my eyes after extended play sessions. Along with my more muted color scheme, the realism aspect also can often override the shade relations of certain blocks. (For example, the upcoming copper ore is coppery in color, but in reality is mostly oxidized when found in nature, and thus will be bluish green on my pack.)
Part of my design for years has also been to separate naturally-occuring textures (primarily used for natural environments) from crafted textures (primarily used for building), with natural textures having designs and color schemes that blend well with the environments they naturally spawn in. As bone is naturally generated in darker or earthy-colored areas like the soul sand wastes, underground, deserts, swamps, etc. I went with a darker, more realistic shade that blended in better with those environments.
Unfortunately with as much emergent gameplay as Minecraft has, it's pretty much an impossible task to predict how players will use materials in ways that may not have been originally intended (like using bone as a substitute for quartz). Different players will come up with different uses for materials in their builds and designing a texture pack to please everyone is not really doable. The best I can do is focus on maintaining consistency of the design principles that have been long-established in my pack, and encourage people to edit the pack to suit their needs. Over the years I've provided many alternate textures which should be easy to find on my Discord server, if not on this thread. Once I'm all caught up with updates and just working on extra features and improvements, I'll also be doing alternate texture commissions through my Patreon.
It's nice to be working on the pack again. Current plan is to update every month (closer to weekly on Patreon) until I'm all caught up with 1.16. Then assuming I've beat Mojang's release of 1.17, I'll be releasing snapshots of work for that on Patreon until that goes live officially.
