Here is the federation starship Enterprise NCC-1701-D, Galaxy class. This is the first Star Trek ship I ever built. It's gone through alot of changes over the years. I've made it bigger and added more detail, especially to the nacelles and deflector dish. The saucer section does seperate from the stardrive section. I forgot to take pics of that. I also built one with Digital Design that I like more than this one. So this model will be going through another change soon.
Hmmm I think you got the back %100 and the deflecter is really well done, but I agree with DARK spawn, increasing the scale would probably improve it, and maybe a bit of work on the saucer section I think that could use a bit more detail but overall great work =D
