Dear,dear ... I think you are a little too harsh Hannibal, in your judgment of Nick´s horse. To me it´s looking rather nice. Perhaps a little more shadowing here and there. White horses are rather hard to paint, better to go for a gray with dapples.
Just a thought, the reins are usely resting close to the horse´s neck, without casting a shadow, not until the neck, in the front, gets norrow and the reins are hanging lose you will have a casted shadow.
Well, nobody said it should be easy to paint 30mm figures in an artistic way!
