That supernova effect, with a little modding, could be made into a kick *** explosion effect in game...
Now the ship: Looks pretty good, but it bears a strong resemblence to a songbird...
If you want a XCF (I could do a PSD too, but you would loose the layer modes) with a sample explosion, which is really simple to do in GIMP, I could do it. But I don't know a single thing on how to make explosion effects in FS2.
As for the ship, I know the shape is very similar to a bird. Maybe not a songbird, but I don't remember the name of the one I'm thinking of. Either a turtle-dove or the ones with a huge mouth.
Beware the Canary-class fighter! 
Give it some incredible capabilities and people really will fear it, no matter what it may look like.
Canary-class fighter lol! Funny lol! But it's not a fighter, it's a dropship.

I must say there's still much to do on the model, rouding edges, adding detail, weapons and stuff like that.
