They looked very good in 3-up form. Much better than their medieval crusades stuff. Less cartoony / GW-style.
When I saw them I thought of your criticisms of the knight horses - bony heads etc.

With these I thought they tried to fix that and went too far in the other direction. I'll have to take another look at mongolian-type horses, but I feel the heads are filled out too much - kind of blobby and
more cartoony. And then there's the odd shoulders on one of them.
Apart from that the entire minis look pretty good, but 'that' is a fairly big deal from my POV!
