Finally finished these guys off. Worked up one of the Champions with a few extra bits so I could use him as a Lord on a bike. Painting and photos aren't especially flash but I'm reasonably happy with the final outcome, the Lord is easily the best of the 6.
Next on the painting table are my 10 Flesh Hounds and 3 CSM carrying Plasma Guns. After that it really depends on the budget but if I can swing it a Bloodthirster or Lord on a Juggarnaut will be getting added to the collection. Hopefully my 6 new Obliterators turn up soon as well..
