As has been said, you're using far too many polys.
Consider having two different models - a ship model consisting of, say, 800-1000 polys, plus a cockpit model.
The bottom line is, the in-cockpit screenshot doesn't look very good. By having two separate, purpose-built models you should be able to get them both to look good. Plus, you won't be rendering the entire ship when you're sat inside and can't actually see any of it.
