As you can see I've carved out a chaos symbol for the front gate, added a few touches to the guns and lights, and included edged grill work to the rear portion. Eventually I will include the engine piece here and plan on adding more Chaos type bits to the tank.
That's it for today for Chaos. With Eldar coming out soon I've been looking at my models and contemplating making the switch to the larger bases for my Wraithguard. Really looking forward to it!
