Question: should we be working on UI (user interface; buttons, sliders, etc) textures as well? That's generally one of the more difficult parts of texture packs, so it's good to know if that's a goal for this one. I will say that if you are looking to publish this on the Marketplace, it will probably require UI.
And if you do plan for this to be on the Marketplace, people should privately message you from now on (email, private forum conversation, Discord DM, etc) with the textures. This is to prevent the textures from being publicly visible and therefore making the texture pack (in a way) free instead of however many minecoins it costs in the Marketplace.
