Nice one ken! I love to do these too
A couple of tips:
1 - gradient on the side of the windshield is wasted IMO, lot of colors there that aren't contributing much
2 - the box with 2 glowy circles in it is a really boring look for your rear engine - if your rear fins were planes (or maybe just the front edges were planes) you would have a few extra quads left over to dress up those engines!
3 - give the back of the rear fins a little bit more UV space - not much, but a slight change should have the light edges rendering out a lot better even at small resolutions. Doesn't need much!
4 - I assume the ship will never be seen from the bottom
A little less space given to the largely flat and featureless windshield could have meant a detailed bottom for fancy in-game animations like barrel rolls.
That said, your shading in general is pretty inspired and spot on - great edge highlights and plane lighting, the white windshield front is bold and works perfectly. the yellow tint to the highlights works great, and most of the detail work really does the job, especially the hinge-type thing for the windshield. You should run this bad boy through Pepakura Designer!
