Portrait of Mistress Ariana Chevalier

ms_ariana

As befits her name, this portrait shows New York Mistress Ariana as equestrienne, in jacket, gloves and breeches, training her pony-boy at a warm exotic location, maybe a hacienda. He is harnessed in a bizarre horse-head costume and ready to pull her pony-trap, with another just to the side.

But is he merely a pony-boy?
Surely this one is a unicorn? And rare enough to be the unicorn that has commissioned this painting!
