Seems like a perfectly good response to me.
Now should have Jagex reviewed it? Of course. However, there’s just this mistrust in art now. I’ve commissioned two things from artists. I asked both, as for my work I want to fund actual artists. However as these tools get better, I’m concerned that trust won’t be good enough.
Fake edit: “Well if it’s so good you can’t tell the difference then why’s it matter” completely misses the point so let’s not bother with that.
