Thanks for all the comments so far.  I appreciate them.

I finished up the interior today, adding an oil wash over some of the furniture pieces and sealing it up.  It's almost sad how little of this detail will be visible in the final model, but I think it was good practice.

I had some issues with the wash.  I originally painted everything in Testors Enamels, then sealed it with Future.  But my Future seal must not have been complete or fully dry, because when I did the oil wash (with oil paints and some mineral spirits) I still pulled up a little of the original paint in spots.  Next time, I need to be more careful to get a full coat of future on everything, clearly a missed a few corners and such.

Below is the completed interior

And here she is all sealed up, to be installed in the main body of the Nautilus
