... having said that. I'm going out on a limb. You've captured a real strong sense of movement. The composition and dynamics are good. The large flat area behind the left horses' shoulder is annoying, in that it distracts from the fluidity you've created throughout the rest of the piece. In contrast, the flat area to the right works well as a foil to the textured style.
