Yes, I have a dream horse. His name is Dynamite, and he's a Quarter Horse Thoroughbred Stallion. So basically, the backstory to this "story" is Dynamite was bullied by other horses and their riders, this is just before a race, but he has had enough (as horses sometimes do) so he decided to train himself in secret, becoming stronger and faster than the other horses and riders. I am not in this art because I couldn't make the rider's figure correct.
All by me except the backdrop, I was too lazy to actually make one. :3 Hope you like(d) it!
