As always, I'm not the biggest fan of the modular, ships-are-just-bigger-or-smaller-version-of-each-other design style. However, these do all look amazing.
The Barrier Gate HF and VHF need some more visual distinction between each other, especially from the rear view. Same with the Heisenberg VHF and bomber.
Maybe also try slightly lengthening the ventral fin on the BG HF and VHF.
