I spend time watching people train horses. One of the things they often do is exercise the horse on a longe line. It easier for the horse to balance without a rider on his back. Trying to paint this includes thinking about how the muscles work and where the light hits the body. I also think about what is going on in the horses mind and try to capture that mood in the painting. This is a nervous young mare who is trying to trust a new trainer. She has lots of energy and I hope the painting conveys that.
