WOW! Oh WOW!
That is just... the appropriate word would probably be Japanese because I can't come up with any english word to describe this as they are all inadequite. I could see something like this in the movie Wing Commander or Starship Troopers (or a live action version of Space Battleship Yamato perhaps).
Do you plan to do a little light weathering on it? Plus, I think a ship like this needs at least a big black or white number near the bow since even with the SF flair, it does share lines and shapes with a modern Navy based ship.
BTW, I love the Pug as it is the perfect description for that craft (so ugly it is lovable).

Do you plan to put any cargo pods on the hangar deck or maybe a couple space suited deck crew figures? Something to help give it a sense of identifiable scale anyway (to a causual observer if it ever gets displayed publicly). Keep it up sir!
