Actually, Lukerobin, they do have a decent point; if I was with Section 31, I'd be disenclined to use standard (or modified variants of) federation starships. What I could suggest is perhaps keep this as reference, textures & all, and build a fresh model of your own design from scratch. You have the skills, I think... ;)
Anyways, this is looking pretty neat. Not sure I'm fond of the random glowy portions, though.
Best of luck,
