Well done! It feels futuristic! Looks great. I really wish we got to see the Galaxy Class gig. I was looking at the TNG blue prints, and it shows the top- in that version, it looks like it's flight orientation is different then yours- and probert's painting. I like both none-the-less.
My one critisism invloves the RCS. I don't get the "X" patern. Byt whatever.
