Image Source Help?

Hi, I don't usually post in the forums so sorry if I'm not adhering to rules exactly, but I was just wondering if anyone could help me find the source of this rendered image?
http://hendrix7733.deviantart.com/art/Sa-chan-with-Gintoki-336317929

I've had no luck with reverse image searching and perusing other image boards and going through relevant tags. Any help is greatly appreciated thank you!

You shouldn't use the forums for things like this, message someone.

Regardless, it's not much of a render considering the original has a plain white background. Also, the idiot deleted gintoki's thighs.
