Though I am not a fan of this design personally, you have done an awesome job of work and detail in the texturing on this beast. You have definately earned a cookie for it.
Nice Job.

The only thing I would suggest is the Starfleet symbols on the engines look out of place. Perhaps either size them down a bit or have something else there all together, a grill of some kind or something of that nature. Also a circular window here and there would give it a good look as well.
On both, just a suggestion to consider.
