Looks great Becco, like your Sun light too. That walkway render is a beauty also, model is really looking sharp. I like the detail seen at the back walkway door!
Update on Walker: I finished the engine in the rear, worked on the neck, and did some basic head points. UV mapped the body, as per your suggestion, baked it and added a touch of zinc, So there is no AO activated in this render.
