Hi, I've been working on a 16px texture pack; initially for MineClone2. But, I also have support for Minetest Game.
My goal was to recapture the Minecraft aesthetic; similar to the Faithful TP. However, I prefer TPs that are libre licensed, & 16px resolution.
So, I've used a lot of references to get the textures pretty close to that Minecraft aesthetic. But, everything's been drawn from scratch over the past year or so(Late July 2017).
I've also worked on "improving" the visibility of some nodes/items in an attempt to make them easily distinguishable; as well as aligning them with my personal preference.
This is still a WIP, and textures may be subject to lots of tweaks. However, it's currently up-to-date,(as of Feb. 11, 2019).
For now, I'm working on the occasional fix; or update as 5.0-dev or MCL2 is developed and adds nodes. I will continue working on these TPs at a leisurely pace, but I figured the 98% mark justifies an early WIP preview.

Latest edit:
A new combined version of my texture packs thanks to Wuzzy; for adjusting some texture names in MineClone2 which removed some clashes with MTG textures.
Updated texture names to combine TPs, bed wood textures, and blueberries; and lastly I added some mob helmet textures I forgot about.
