Hmm -- it's not a bad ship, but I think it could be considerably more phallic. Have a look at the R-Type ship for instance:
Battle Garegga, another classic, also gets the job done:
The Yakouga games are a bit more direct on this front, but they're always a great source of inspiration.
On a more serious note though, I think it would look a bit more slick if the two outside "heads" (of the three spires in the front) were a bit smaller, to make the cockpit stand out more, and maybe the "tail feathers" were faced just a bit more back. Take my suggestions with a grain of salt though. I'm not a ship designer. What color scheme are you going to go for?
