This, along with many other pictures were tagged as made by the artist itoh_ben, and since there were no search results at all here on Danbooru, I'm thinking that maybe the artist's work is banned for some reason. However, I didn't find his name amongst the banned tags, so I'll just put this one here for someone else to confirm wether these pictures are okay or not.
The reason for that is because the other images are tagged itou_ben here. Using "h" to represent long vowels in Japanese names isn't standard on Danbooru, and so "Itou" is preferred over "Itoh".
