@Muun: For the sake of the horse, please use a ref
I thought about some furture police horse, but I am not sure if thats a little too far of the road.
Better a real battle horse ?
Most of them feel rather classy, like 1 and 4. A little spikey though.
#2 Has an interesting helmet
#7 A little warlok like with the skulls on the rope.
#12 A paladin ?
#13 An african lion horse ^^
Same method as with the scythe, idea finding with shilouet studies. (I tried to give it a little more professional look than just a blank page. XD)
