First of all, Let me say HAPPY NEW YEAR!!
When I was a kid, Galactica was one of the first scifi movies that I watched, at the end of 70´s. The remake is fairlly superior than the original series, which appears that will have his own reboot too. Read about it here. Bryan Singer is on board, as Glenn A. Larson!
Galactica´s Universe has it´s own ships and concept drawings, as a LOT of fan drawings too. Here you can see Ray Lai´s work, done for the new tv series. Many other peoples done his own sketches, like Richard Livingstone:

I´m not a prof, but I did my own ships too 😀

There is an excellent forum which the focus is Galactica´s Universe: Wolf Shipyards. Say hello there!!
