I'm using an Arachnorok to count as a Trukk for my Boyz. This is still very work in progress, and I will be adding the wooden framework to give my Orks somewhere to sit.
My wife and my cat both hate this model. My cat jumped up on the table, saw this, her eyes got big and she fell off the couch backwards. My wife wants it kept in a side room. It's pretty funny.
I'm experimenting with color schemes right now. I might end up using some of the poison dart frog color schemes for inspiration. I'm looking for something really bright that screams "I'm super dangerous!"
