Create an image of a mythical creature playing a competitive sport in a vibrant, otherworldly painting.

Imagine a vibrant and surreal painting. It has iridescent colors swirled together, with nuances of late 19th century artistic techniques such as those by the Impressionists. Deep in the heart of the fantastical scenery, a mythical creature, like a majestic griffon with its leonine body and aquiline head, partakes in a competitive sport. Attired in a shining armor, this griffon is seen playing soccer with concentration and agility, the ball brightly contrasting against its golden body. The entire scene is illuminated by an otherworldly glow, breathing life into this surreal fantasy.
