Lone Rider

This is a story I wrote in class, they gave me a picture, and I had to write a very descriptive sentence about said picture.

The lone rider and his tenacious and faithful stallion galloped fearlessly along the empty, grassy plain, beside treacherous waters. The misty sky hid a golden sunset, and the horse's hooves, that pounded the earth with power matched only by the roaring ocean, could be heard a mile away. A salty smell lingered in the damp, sea air and, as the horse ran, he threw a wild tempest of dust in his wake. The stalwart rider was shrouded in creeping shadows from the retiring sunlight, as he journeys tirelessly toward his destination.
