I like the tech asymmetries and the unusual "chin." It almost looks like a pontoon. I like the winglessness -- this isn't a combat ship. It's a clunker with a job to do. Might also be cool if it were a different color. Dark gray or charcoal or even bone colored or something else. On the con side, I don't like the Romulan-like double neck.
I like the bone-colored suggestion. I'm having trouble imagining where the warp systems are though, and I have to agree about that double neck; it looks too Romulan. That chin, on the other hand, is brilliant!
Looks great. Love the detailing. Definitely still looks Klingon but not one of their warships. Nice work!
