I was going to say your lighting needs some work...
I recently dug out this old composition and loaded it into a newer rendering package with more robust lighting parameters, specifically, point source lights. I placed a few at low angles (like under consoles) and within the "tube chamber".
That light within the chamber even casts a shadow from the grille upon the deck.
Yes the darker feel is so much better. Reminds me of the lighting on ENT which while modern is very dynamic and more realistic.
