He basically uses a method where he stitches bits and pieces of art from other artist to make his own, like stitching As109's Alley Girl's head onto another body. Also look at how vastly different the art style is from picture to picture, it's not consistent.
There were other sources of him copying, like the one with Mai's feet, but I can't find it at the moment. He got flack and wiped so there's that. This artist is a fraud simple as that.
