Sagacious wolf Horo is illustrated rather impressively above; below you can see a pair of photographs bearing a suspicious resemblance to the good wolf.
Could somebody have perhaps posed them after seeing the fine work above?
Tribute rather than plagiarism, surely.
The artist in question is Hisahiko.
See also Horo classically “painted” for another example of a more original (in that case, Type-Moon) art style applied to the business of nude wolf illustration…
