Uhhhh

Yeah

don't trace someone's art without permission especially when you know them because sooner or later they WILL find out

And it's just disrespectful for an artist to draw something and someone else just taking it if you want to use it as a reference fine but if you're using it as a full on base then credit the artist please having your art traced is not a good feeling and it's actually irritable

I shouldn't have to tell you guys this
