When you do the rank and file boys, I think its a must to have some fights in the back ranks. Its over-the-top fun if you ask me. It makes for good character in the unit and keeps the rank and file interesting especially in the back ranks.
For the first fight scene, I wanted to essentially keep it simple. Here I am just starting to work with these models for the first time and I've just built a few of the boyz to get the general hang of the pieces. It takes me a bit to get into the flow of them, to see what works, what doesn't, what joints can be manipulated, etc.
