Hiya.
Nice design on the ship, but there are some things I'd like to mention. Since this really is a low spec section, you should optimize that ship a little.
After studying your model I found loads of places where you could cut lots of triangles from this. First of all, delete all triangles that are inside the ship and hidden. For example the inside ends of the angel wings, and inside polies of the "tube" that hold your jets. Also, you really don't need that much polies for the cocpit in my opinion. And I mean in both top view and front view. Your model stands currently at 694 triangles, but you could do this with 500. But if you don't feel like cutting that much just stick with deleting the absolutely no-use ones.
Cheers
