PROOF: http://www.furaffinity.net/view/6527410 (NSFW) , four poses traced from http://www.posemaniacs.com/archives/1566 , http://www.posemaniacs.com/archives/374 , http://www.posemaniacs.com/archives/174 , and http://www.posemaniacs.com/archives/66
And here is an overlay: http://www.star-soup.com/images/etc/juindalo-overlay.png
Just to be clear, I didn't commission him or anything. I just found him through the favorites of other people who had been watching me.
I saw this image: http://www.furaffinity.net/view/6527410 (NSFW) and noticed that pose #3 was vaguely familiar. So I looked on my favorite reference website, and there it was.
Posemaniacs is an amazing art reference website filled with all sorts of poses from many angles. And you can click-drag across each pose to rotate it. I use it frequently to reference some poses/angles, or to get some inspiration if I have none. It's an awesome tool.
But this guy isn't just referencing, he's straight-up tracing. As you can see from the overlay, #2-4 are traces. #5 has some changes, so it's not completely a trace. I don't recognize pose #1, so it's possible that he did it himself.
I poked around in his gallery, and nothing else really stuck out for me, but I kind of have the mentality of if someone has one traced image in their gallery, it's possible that there may be more. But, a good portion of it is porn, and good luck trying to find those specific pictures. XD
I wasn't sure if this would be better here, or in art_theft. But I figure that because he's making money off of these, it might do better here.
