I really like the attempt to realize the earlier concepts.
And the work is very well done indeed. I like!
I'm not too keen on the style of the nacelles.
Maybe I'm getting the bad aftertaste of the nacelles off the Abramsprise. Or perhaps they look too much like the engines off a Tomcat or Phantom jet fighter.
The intakes, the cowlings, seem too much like conventional propulsion elements rather than warp drive components. Just my personal take.
And yet...the nacelle work IS quite nicely done!
Look forward to seeing more art on the model.
