Congratulation, snagy!!
Very nice painting; I realize how difficult it is to paint details of the hereldy on a 30mm sifure size !!! Could not do better myself.... The lights are painted in the same directon as your miain light source, from the right..
Small detail: please note that the white painting of the eye pupil of the horse is not realistic, too large and visible and never so apparent such as human beings... Look at several pictures of real horse eyes on the net to adjust a bit instead of a cartoon interpretation affecting a very little your realistic 3-D painting of the knight !
