seconded!
but those thrusters....
arent they...rather EXTREME???
Maybe this ship is built for exploring gas giants.. judging by the oberth nacelles i'd say it really makes it look like exporer type ship.. maybe a modern replacement for oberth from the ambassador / enterprise C era?
Speaking of bottom, perhaps you could cut it flat and blend it into under-saucer-dome nicely, and put a vertically-mounted downwards pointing deflector dish, perhaps add texturing to indicate that the ship can LAND (like the voyager)
