I like the body of the ship so much I gotta give this a 5! The very front and the rear engines could be better I think... actually it would be perfect if there was a rear engine section at least half as long as the rest of the ship. Very nice!
I disagree with Willis -- the side engines do contribute a lot to this model. As usual for you it's very well shaped, with that neat hunched-over look in the front where the top curves down to meet the windscreen. Great job!
