I then drybrushed the model to accentuate the detail and highlight certain areas.
Here is the Wartrakk with it's cousin.
I started on the rider. I didn't want to use the standard rider which comes with the plastic Wartrakk model, so I used the legs and added the right arm from the rider to the standard torso from one of the plastic Ork Boyz. I added a left arm hand weapon, partly because I had run out of Shooty Boyz weaponry and partly because it is different. The head is also from the Ork Boyz sprue.
I will be giving him a black undercoat.
I gave the rear gunner a black undercoat, though I am painting three up (I had a spare from a Grot Bomb Launcha).
