Here’s a snapshot of the current state. I have done work to improve the gesture of the piece, trying to add more strength to the pose (rearing higher, chest out, arm back, twisted more, etc).
Also more attention to the legs – it is important to understand the bones, tendons, and ligaments in a horses legs, as they are the primary forms below the knee and elbow. Beyond this there is still a “softening” pass, that includes veins wrinkles and those small variations that keep anatomical forms from being perfectly smooth. And obviously I am going to have to address the hair and tail at some point. Perhaps soon?
