Well as you said "the texturing is wrong" and some chunks (like the four front prongs) had odd angles with the UV map alignments.
Anyhow, GTVIDn Wraith? That's a mouthful, the GTI didn't have special prefixes for their ships but did use a Norse naming convention.
So....
GTD Tyr...
Tyr lost his hand, etc. etc. dealt with a serpent I believe and betrayal by Loki.
Since allied intelligence wants as little to do with the GTI as possible, such a ship named after the betrayal of Loki (the old regieme) works well.
On where to add detail, I'd say on the back section the two "sub space taps" could use some detail to avoid the surfaces seeming so flat.
Some of the tile texture areas I'd work as outrisings, and I'd add in some wire sections like on the Millenium Falcon in Star Wars.
The fighterbay looks great, with some red warning lights and loading docks worked in, sweetness.
Finally, on the ship nameplate *please* use the STOP typefont which is used on all FS craft
