A little design, among others that i've been working on for 'Interstellar Marines'.
It's basically a set of modular elements, so its been a hassle to come up both with a method to have almost all the pieces seamlessly attach to eachother, but i think the result is well worth it.
Photoshop cs 5 and Sketchup used on this one, the fake GI is actually a real render, kinda cheating but whatever gets the job done the fastest way possible right? :)
