Looks like saracen archery but the archer should have used the right side of the bow. I think cultures fighting styles should differ like this. Aserai master archers can have this as a unique skill. Khuzait archers and horse archers might use the right side as well. Battanian Fianns might have longer range and better accuracy etc. etc. Some unique fighting styles would be cool.
