The bomber isn't just a pretty face. Someone decided that giving a dire troll explosives was a good idea, and I'm inclined to agree. In a Gunnbjorn list he gets to drop two high-pow and large aoe hits a turn.
The blue skintone was done the same as Gunnbjorn. I started with shadow grey, 50/50 shadow/space wolf mix, blue wash, and more mix. The pinker hands and belly is a final highlight with watered down elf flesh. (mmmm....tasty elf flesh...)
Being a shooty troll, Andre wears a blue tartan. Painting plaid is slightly easier than diamonds, slightly.
Being a plastic kit was nice, as the whole thing went together well, and he doesn't fall over and crush things. There was just the usual troll neck-gap and minor flash. I also found a pack of snakes who will be sprinkled across the army.
