for what it's worth ... me likey very much.
Only critique -- probably coming from the Trekkie in me -- is it seems the leading edge of the engines need something to "enhance" the "shoulders." If not Madonna-esque bullet bra contraptions, maybe a little grill work or a half glowey globe or something.
Technical terminology, don'tcha know.
But, you get the idea: just something -- even a greebly -- to help add back some sense of forward motion, even when it's standing still, as you had in the previous iteration.
Just a thought.
But, overall, I love this rendering. And I really like the deployable "sails". Best of both worlds.
