Yea, I think you're right. The door is reflecting so much light it makes it look bare. It's actually kinda surprising that it's actually that clean!
The other thing thats throwing me is that if you go to that link and look at the pics, it's actually two different aircraft. One appears to have white or light grey colored struts while the other seems to have dark grey struts. I think I'll keep it simple and make it all a light grey. I'd be willing to bet that's the way it would be anyway.
