Well a while back I did actually put the torpedo launchers inside the secondary hull but it just didn't do it for me. I guess I could try and give some curve to the launcher. I do like the look of it sticking out of the bottom though, and without it there, the secondary hull looks like it needs something there...
I believe that some curve can make it to look more... natural.
The ship has elegant and smoothed lines, rounded in general. Just the torp is in the square direction, and it breaks the design flow.
