Yeah, I'm starting to get suspicious as well, because the only things I can find so far are the Herbalist Mantle (which is weird on its own, but their story is that the commissioner provided the sketch, and if it's a one-off instance, I'm willing to believe that) and the allegedly-AI backgrounds (which can't actually be AI because of the upload dates on their dA). If they actually have a history of tracing outside those two things, then I'd probably swing back around on them, but I haven't seen any proof.
