Hi! if you're considering doing game dev seriously, I'd highly recommend experimenting with your own art style (could even be simple or similar to this one) and try your best to create your own assets, however if it's just for fun or a hobby then you can use my textures as long as you credit me somewhere in the game (and wherever you post it to if you share it)

TL;DR you may use my textures + my opinion :)

Thanks again, I always try to keep the vanila "essence" of minecraft in my packs, which I feel is what makes them unique from other packs in the genre

Hey, good news, yeah! the 1.21 update is on its way and up to date for the most recent snapshot as of me commenting. (I wait until the updates are actually out to post them though so I'm not constantly rushing to update for weekly snapshots) Thankfully I've been able to work on it more despite being a college student, my OCD (not oCd, actual OCD lol) had advanced to the point where it was debilitating and I wasn't able to do much but thankfully now its being treated and I can function better, allowing me to work on this more.
