This is fantastic in so many ways! Enjoyed the progress shots, thanks for sharing those. One thing...the bottom of painting where you stopped the body of the horse...maybe continue the body to the lower right corner, even very subtle or blurry. Because the way it is now looks just like how a taxidermy mount of a deer would look hanging on wall, and Im pretty sure you dont want that
Its very well done, the white'ish coat, the head gear, the eyes, the simplicity....love it all.
