Here is the federation starship Voyager NCC-74656, Intrepid class. The warp nacelles can be raised to simulate warp travel. I use the diagrams in the Star Trek magazines to build most of my models. I need to work on the ram scoops on the nacelles.
Slick.
You've really captured the look of the original, however I would remove the wedges as they look out of place against the layered plates. Still, a bang up job.
