Guys thanks allot for your comments and suggestions so far, so i initially made the necelles longer in the middle and overall they look quite nice now... although WZ you are right anout detailing the end with summat.. thats what im gonna work on next.
I have angled the front so its not so sheer and looks more flat and added an extra ring to the inside, i have shrunk the impulse (had to rebuild the saucer around it
) and i have lowered the hull away from the saucer, thus allowing the neck to have a nice torp launcher. I have also begun shaping the shuttle bay.
Your suggestions so far have helped mold this model, thanks for the input
