I have some axe/pickaxe animations done, but they are for a new pack I'm doing for crafting. It will come out soon.
I usually add assorted stuff from all packs to this main pack, but animations are not one of them.
Regarding the price point, unfortunately free packs don't sell a lot (almost nothing), so making them free will render me out of the art asset creation business as it will become non profitable for me in the long run.
I already set low prices (ofc this depends on the country you live) exactly so that everyone can have them, without breaking the bank.
But I really do appreciate the enthusiasm shown by you regarding this pack.
