Studying these images and sketching last night I can see contradictions. The most familiar view of the ship (as seen from above) leads one to think that the wings flow back from the nose and flare out yet fixed above the main body. But seen from below that's not how the ship is drawn. Seen from below we don't see a discernible fuselage separate from the wings. As drawn it looks like the wings are much thicker and merged with the protruding forward section. The ship is more manta ray like than bird or airplane like. I don't have a problem with that, but it makes reconciling the top view a challenge. Granted annimated ships are stylized and simplified, but a simple extra line easily added to the bottom view would have made a big difference and yet it's not there. It could be that what we're seeing from above is more of a painting scheme rather than hard lines or shapes. Also the bottom and top surfaces each appear to have a subtle crest or ridge to them as evidenced by a continuous line from bow to stern.
