Spaceship Realism

Can anyone point me to a tutorial that covers space ship realism. Or give me some tips on how to achieve “that look”. I have been searching for about three days now and I just can’t seem to find the information I need.

Daniel Brown CGI (YouTube) comes fairly close, but I feel we could do better.

Besides hardsurface modeling ? I’d say to get familiar with displacement, very very familiar because sci-fi loves its greebels.
