If you never saw Doug Drexler's Wordpress blog, you were missing out on a great resource of ship renders, concept art, and behind-the-scenes info. Unfortunately, it's now gone. Read about it here:
It seems that some other VFX artists took issue with him putting "Drex Files" on all the images, and felt he was taking credit for them. I can understand that to a point, but he was also going out of his way in the article text to say who did all the work for each design/render.
Even though Doug hadn't updated it recently, I hope it comes back in some form. I'd hate to lose access to all those amazing images!
