Phew... finally nothing yaoi-related. I like both of them, escpecially Thassarian, but not as a couple. It just... does not seem right with them treating each other like brothers in arms and the closest thing to a friend a death knight has.
You did escpecially well on the beard, brows and hair. I think drawing hair can be kind of difficult because while armors and swords are geomtric forms for the most part and you can easily measure everything it is something else with hair. While it should not look too straggly it should neither look too sleek and even. It needs structure but a subtle one. Everything else looks great aswell but nicely drawn hair or beards always catch my eye because this is something most people are not good at.
Ah I just love these two little badasses. <3 With every character I played I always did every single quest they gave me and always looked forward to questing in Western Plaguelands, Borean Tundra and Icecrown. Not the usual "Do this and I will love you to death for saving me!" with their snarky attitude.
