Breathtaking work, my friend! The first time I took a better look at this lady I couldn't find words to say. The exterior is just perfect, and considering how huge this ship is... well done.
I really like the interior, for several reasons. One is that it's not that huge. There is a lot in it indeed, but it is nicely distrubuted. The only booboo I can mention is that corridors are a bit long, which I can understand given the enormous sizes. Just a thought. I wouldn't even say it needs to be fixed, because it's a necessity.
You won me with the transporter room. I jumped into the shio blind, not having read the description and I screamed in joy: STARGATE! YISS!
The hidden turrents are lovely.
Also, now that I actually read your description I know what it is based on, still I would like to share something: at first I thought it had some connection to Hallgrímskirkja in Reykjavik. - I think the name tricked me into believeing it. ^^"
Concluding: Prefetto! I love it. A true gem, a piece of art.
