Looking great as always, dude.
I've been thinking over the last couple days about that idea you had for the thingies near the back of the nacelle to move in and out. At first I wasn't keen on the idea but then I realized it does make sense. Having it move in at high warp would make the ship more "streamlined" and would (I'm guessing here) make the warp field more smooth. So, it's a cool idea.
