Maybe one with the Valhalla type saucer would also look nice. I like the deeper 'chest' on the secondary hull' than original. You keep the teardrop shape well. The best thing is that you gave the secondary hull "shoulders" to aid the nacelle supports. I really dig that. You keep the secondary hull fluid but add just enough complexity to the hull to keep the eye moving. Gabe Koerner's Enterprise might have done a bit much in that regard for some, but you are getting that formula down very well. The Valhalla saucer will help mirror the fluid lines on that secondary hull.
