well I agree. if one part is shaded with one way and the rest of the ship is not, then the overall outcome would not be that clever looking. Then again it goes vice-versa, so using parts without shading in ships that are using shading as technique, the thing just wouldn't look good.
I could pressume and assume and wish that our ranks would be skillfull enough to make their own judgment about the matter, but self-deception is not my virtues
So I suggest you do both versions; one for each style?
