Someone had sent me a link to an article explaining and showing that No Game No Life artwork was traced. As you can see, the opinions on this matter are quite diverse. Some people take offensive in this matter and others say it doesn’t matter.
And in a way, it doesn’t. It doesn’t matter if you think “o my gosh how cool, I wanna draw my characters like that.”
But if you’re putting your work in an informal place everyone can see them, you should give proper credit. And if you’re actually publishing your work and making profit from it, you should have permission to trace and and actually you shouldn’t trace at all.
Just a few words I wanted to say.
