Ive been keeping tabs on your work, just havent found anything to respond to until now
If you're having difficulty "picturing" what shape you need to come up with, i suggest looking through the 2d and 3d galleries until you find blue prints or sketches that you like, and try modeling from that. i suggest waiting until you have a vacation from work/school/holiday so you have plenty of time for trial and error. Personally, i have dabbled in 3d myself, using max 7, but i have no time to learn properly
, so i just give feedback and advice to others. I am a little dissapointed with your bridge, i was expecting that the kitbash you had was merely a stand-in so you could model your bridge using that as a reference.
And when do you see an insignia class ship?
