They're pretty good.
They work surprisingly well, I would never had thought to use elves to make R.Rs.
Anywho, the conversions look really good, and the paintjob is pretty nice (about the same as my level, so I'm using that as a comparison,
not others dakkaites)
My only fault is that the steeds still look a touch too elven; I would say if you are going to do it again, remove mre of the armour plates and crests, or make more crude and human-ey.
Aside from that, pretty awesome -
