I like to mix it up with the size of the model and the size of the weapon including the type of role the model has. Take this one. He’s big, muscular and a brute put simply. Though he’s not wielding a big ass weapon just a compact grenade launcher. Okay, enough about that 😉
I’ve smoothed over the parts that would expose it as a nid.
I really like the distorted muscles so I just added pouches and stuff instead of messing up the back.
