The goal for this resource pack is to provide Minecraft with a more appealing and defined visual experience; just enough to retain the pixel-art aesthetic of the game, but with a high enough resolution that there isn't a constant shortage of pixel definition. I think 32x is the perfect resolution for this goal.
As for the aesthetic design of the textures, they're semi-faithful; they don't deviate from the default appearance to the point of being completely unrecognizable, but their style is somewhat different, and more realistic. Everything is produced with a higher standard of quality, with more harmonious visuals and higher levels of detail. The texture designs are made with logic and immersion in mind, based on their crafting recipes (if any) and their uses. Basically, this pack is what Minecraft might have looked like if someone who knew what they were doing made its textures.
