Here's no (possibly) right category for this, but in my opinion this doesn't need to be viewed only by over 18 years old persons.
It's a demon stallion, how unique... For me it is because of that breaking scrag, what's not so common theme as it should be; via my eyes even a normal dressage looks horrific, the horse is forced to a stupid position what can't be any good for it. Possibly this is a previous dressage horse, a famous one, who got bored enough to suffer from stupid curb bits and hands pulling his jawbone into his chest. But being a long-toothed demon doesn't rescue him from breaking scrag. You see. Neck vertebraes are sticking out through his skin.
