Thanks mate, just got back from Greece, so will be working on this heavily over the next few days.
You will have to point them out to me mate, as im unsure as to where you mean exactly.
I am also using the font FederationBold which is the most accurate for most of the hull writing, bar the registry No, any help in this area is also greatly appreciated. 
Catch me on MSN for those ;)
Thanks mate, I will get on ASAP.
Cookie for you, good sir.  
Cheers mate
This is just awesome work markyd.  When it comes time to porting, let me know if you need a hand.  I've got max 3.1.
Thanks DJ, I really appreciate the offer.
Good looking impulse drive...is the grille modeled or textured?
Thanks mate, It's textures mate. I have finished with the mesh.
Thanks for all your comments and help fellas, I just got back from greece and am looking forward to a few long days with coffe on these textures over the next few days. While I was on holiday I managed to finish the sketches for the TNG Connie on some "Post-It's" too lol..
