So I am pretty bad at art so I tend to use other premade sprites. However, I dont know how I can protect myself legally if I use these sprites
For example I want to use this sprite:
https://neoriceisgood.deviantart.com/art/100-neorice-monster-sprites-419509727
It says I cant use it for commercial use, but I see people asking whether they can use it in their free games and he/she says yes.
If I want to use that sprite, what is the best legal way to do it?
