I have to say I REALLY like the cables running through the interior! It takes away from the usual "antiseptic" look spaceships tend to have and reminds me of the gritty old rustbuckets I used to sail on! Nice work, Jay, can't wait to see a final render!

Oh yes...as for the symmetry, I am anal for symmetry. If something is asymmetrical, my whole body starts leaning in the direction of asymmetry! :-) Just the same, why not go for something different! As long as the physics of the engine are mildly believable, I suppose it doesn't hurt!

Carry on smartly...!
