Hmm, thats pretty cool. I like the turrets (though i generally think carriers shouldnt have many), they make a nice change, plus the shape of its surface is intresting (those indents especially). Wish i could model...
As for the inards, i think it would be pretty intresting to have a ship you can fly inside. Or even through. Imagine a shivan carrier causing havoc, similar in its storyline to the Sath or lucifer, a few brave GTVA pilots, fly into the mouth of the carrier away from the turrets, target a fighter sitting on its deck, release your bombs, and fly out the other end, just dodging the shockwave from the greatest threat to human existance.

, wish i had the time to make a campaign.
plus you would need a mod to get fighters to sit on the deck. Or maybee they could be classed as turrets? Now theres and idea.
