I'm thinking that the BH BS should be sleeker. If you take the bow of that model Tic displayed in this thread and connect it with the modified stern of your newest model, I think you would have a good looking and functional ship. I think it would look better with a taller, not wider, profile.
Your current model would probably be a nightmare to navigate through an asteroid field. The BS has to travel through "challenging" areas of space from time to time.
Keep up the good work!
Edit: I certainly don't want to be an ingrate about this. I'll be satisfied with whatever you decide works best.
