It's pretty good. I like your style, but here, the white reflexion on horse are too much, too pearly, and eyes can be better circle in black (in a minus way). The work on the blue cloak and armor is really interesting and the silver/pearly armor of the horse is really good.
I value it 6 or 7/10 ; here, it's a 6 because of the base (by equity compraring to my others votes) : take the time to work it, and this mini goes to be very good.
