According to specs and blueprints. Engines are 4.5 meters, cockpit 2.7ish meters Looks somewhat right to me. It´s a fairly small pod, compared to the rest.
Update: Still messing around with textures in general trying to get better spec and gloss definition also working on the lighting. feedback is more than welcome.
