Nice one. I did a fast drawing but your's better. The antennas over there makes sense and the changes to the repetitive parts would make it more distinctive then kirk. If you have more ideas just update your post with new images. But focus on middle body only because that is the only thing missing from his model. We need the model to be complete as a whole before discussing any further what changes to be done here and there.
@Unlucky_Soul, I recommend you to wait some time for other people to give their drawing ideas instead to jump in to modelling a final product. The more ideas the better - for inspiration. If you want you can prepare only middle body part/s (not whole ship) so it will be easier for feedback and less time consuming for you.
Also, Imports are out of the line but if you have some interesting ideas/images from other sci-fi genre but close to Bretonia in terms of model - share them guys. (For example Warhammer: Space Marine's battle barges are flying cathedrals with a lot of Gothic elements close to what Bretonia are using in FL)
