The result is below. It's entitled Wandering Storm and is acrylic on canvas measuring 72 inches x 60 inches. Clearly he's shown some artistic license but the stag itself is very similar to the original image and is very impressive in my opinion.

As well as being a wildlife artist, Matt Ryder is also a very talented caricaturist. His website is well worth a visit. I thought the caricatures of Kim Jong Un and Ian Brown, not 2 names that tend to appear in the same sentence, were particularly good.
