Good work so far DJ!
I can't wait to see it in my engine, the Galaxy class is my favorite ship and currently the SNS Galaxy is my favorite model!
I was wondering if you were done work on the Secondary Hull... I see a few problems... it seems to be too narrow in Width, so the Deflector Dish looks a bit too tall in height.  Also the Main Impulse Engine looks way to short in Height as well, looking very thin.
Anyways, here is a pic of the SNS Galaxy in NanoFX GE, I'd really like to see your model surpass the SNS!
