I hear ya. The most difficult part for me is nacelles. I usually go through 3 or 4 designs before I find something I like and even then am never fully satisfied. In fact, the ship I just posted on friday will probably get new nacelles as the ones posted are bugging me no end.
When you say "dome in front", do you mean a literal dome shape, or just a red bussard of some kind?
Well, I don't know what I want, is the problem.

Having said that, I keep looking at my Enterprise E model here on my desk...
Maybe you could get some inspiration from the rather low quality design I tried to work up before we new exactly what the JJPrise looked like:

Yeah, I remember when you were making those a while back.

Going to go draw some tonight, while watching SyFy.
