The head reminds me of the Stark direwolf sigil from Game of Thrones. The bulk really is not helped by the smooth appearance. I suppose some fur definition could be sculpted in with green stuff.
The Oathmark wolf next to the horse is really jarring to me but maybe painting would reduce that?
The Oathmark wolfrider looks good on the Fenrisian wolf.... but my budget, and my wife, thinks I should just take some plastic chaos hounds in my bits box and convert them to wargs. At least until folks start selling used Oathmark wolfiders on eBay. Of course that means sculpting with green stuff again.
Wolf rider spare bits sprues will be nice to add diversity to goblin infantry builds.
