Critique:
WAAAAYYYYYY too few polies for that class. Also, while it is a nice idea to base the thing off the only really well mapped ship in FS, the shape from the side is kind of

It looks okay in the perspective shot, but overall it's just plain.
Suggestions:
Add more polies
make it "squatter", that is shorter in the vertical axis, do something different with those square things.
you've got a lot of detail in the nose section, spread the wealth, especially on the secondary hulls.
Overall, it's a good start and much better than I could do with TS. I never really seem to have the time or inclination to do the tuts, but I can bang out a decent mesh in Blender okay.
As far as a name, how about GTJ Laerad?
