The lack of source for this image and post #3207869 is the biggest issue here. Even great posts without source have a tougher time being approved.
Without it, we can't confirm where it came from; could be either one of the artist's paid reward sites (my guess is Fantia).
Since the uploader deleted their account and I can't find these images anywhere else that isn't behind a paywall, our only hope is for someone who is subscribed/supporting the artist to stumble across here and set the story straight.
If you guys would like to take a stab at it, there are some resources at help:image source you can use.
