This is the federation starship Enterprise NCC-1701-B, Excelsior class. Originally, this model was the Excelsior. But after Star Trek Generations, I had to turn it into the Enterprise. I had a heck of a time building the ridge on either side of the deflector dish. I couldn't come up with a good design. Trial and error.
the excelsior and the enterprise b are not the same. but the enterprise b was an excelsior class. that missconception was the only thing wrong with your moc, and i can hardly take away points just for that, because the model kicks some klingon butt! i really want to see more star trek models, like say... the enterprise c (yes it showed up once) and maybe the enterprise d and e too, you certainly have the talent for it.
