I did the vast majority of this guy in a day. I did the turret last after a few days off. It's pretty standard desert fare for me, but I did do some fun stuff with the weapons.
The tank proper was standard with the only real big differences being in the guns. He wanted all plasma on this guy. So it has the Executioner turret with plasma sponsons. With the new edition I thought a front hull mounted Heavy Flamer would be fun. Nothing is glued in, so things can be swapped out.
The Shadowsword sponsons should be in soon and I can finish that beast. I have a squad of DKK sitting in water at the moment. Plus a mostly done Sentinel.
