This is truly, truly, the laziest and most stupidest thing ever.
Making a picrew to sell for even real money for is the worst of DeviantArt scams I've ever seen. I don't care if you're unable to draw things for adoptables, either you learn how to draw or don't even join DeviantArt at all. It's very low effort, and I don't care if its detailed because all that these people did was just click on shit until they made something. That ain't art, that's just pure laziness of not doing it yourself and having to rely on other people's artwork on picrew for it.
