Very nice!
So far as the CX goes, how did you decide to model the two-box saucer warp engine? I gather that the Starline 2500 CB mini has it under the back of the saucer,
underneath the impulse engines; but that ship also has a fair bit of added bulk behind the bridge dome which may not match the cleaner lines on Adam's 3D model as well as your current saucer does.
I could picture the DX as the
Kumerian, leading the Klingon task force in Operation Unity (just as
NCC-1776 USS Bunker Hill led the charge for Star Fleet in that campaign).
If you happen to have a Dominator mini on hand, have you considered setting this pair of X-ships up against it in a diorama based on Adam's
Andromeda Atacks! art piece?
And have you thought of doing any other first-generation X-ships going forward? (Personally, I'd love to see the GSX
NCC-1821 USS Sakharov; its half-sibling, the NCC-1783
USS Field Marshal Colin Powell, was featured in
Adam's cover art for Captain's Log #40. Not that I'd expect you to be taking cues from the peanut gallery, of course.)
