Nah, I'm actually very happy with how the render turned out. The hull is a bio-polymer laminate able to heal itself in the case of damage and it is able to absorb high energy hits from DI weapons as well as kinetic impacts. The grey sections are critical areas that are re-enforced with an advanced alloy overlay. The blue is the color of the Caliista Muran's squadron.
Thank you! This was a challenging design to model in Sketchup. Many many hours spent healing geometry errors and aligning textures. And the worst part...it's not finished!
