The new ship isn't designed as a functional, 3D mechanism, it's designed as a piece of 2D graphic art, with all the trademark foibles that go along with that... and that includes the "big bold curvy-shape high-lights for visual interest" one.
I don't want to see a movie with a boringly functional space ship, if we went for pure function over visually interesting, we woudn't be drooling over Vectors work here !!
Actually, that's why so many people like his work so much... though it's done with a clear eye to "style," it's also done with a clear eye to practicality (or rather, "fictional practicality" I 'spose).
Virtually every detail added is there or a reason. All of them are FICTIONAL reasons, but they're still reasons nevertheless. His work looks like a machine... but a well-designed, artistically-styled machine.
Seeing that... a proper fusion of "style" and "substance"... is what I, and lots of other folks, like. I just don't get that from the ST'09 design. I see lots of style for its own sake, but very little real thought behind it.
Vektor's 1701, by contrast, has both. As does his Grandeur.
