Okay, as some people got me thinking what body to add to the turret (http://flaketom.deviantart.com/art/WIPWIPWIP-252789725) I've done and I can't really decide what I wanna do, I thought I could just go for it and let you do the work and give it a body/hull of your choice.
So you may be interested a bit more I do a small contest and the creator of the design I like the most, gets a model of his likes from me (if he cares...) and my eternal blessings.
