The link goes through a free-hosting site and then redirects to an unfamiliar vendor's site, where the artist's name is NOT listed on the page. So, I can't be sure who originally put together this design.

I don't usually buy fan-art ... but if I were, I would probably try to find out who made the design, before I'd consider purchasing from a vendor that the creator themselves chose to sell through.

I found a London-based Etsy shop selling the same design, among others (and complaining about "other shops stealing" the designs). — But that Etsy shop doesn't list an artist's personal name either (just the shop name), from what I can see. ... So, again, I can't shake a little bit of suspicion. I still can't be 100% sure whose design this was, so I can't be 100% sure that I'd be buying from a vendor which that person chose to sell through.
