Strength and Grace in One Frame

Riding strength and grace in one frame. A moment where power meets pure elegance. PROMPT: A 29-year-old man sitting on a majestic white horse, possibly a Gypsy Vanner or Friesian, with a very long, flowing white mane and tail, rearing up on its hind legs in a grassy field. It has a bridle with dark leather straps and brass hardware. The horse's powerful build and feathered hooves are prominent. The man is wearing the outfit as in the uploaded photo. In the background behind the horse stands a beautiful castle.
