I like it.
The smoothing groups are really ****ed. What 3D app do you use?
Try selecting the model ( in poly mode), and remove all smoothinggroups, then select a part of the model ( 1 wing, intake, nose, cockpit, whatever...) and apply one smoothinggroup. Rinse and repeat for the rest of the model.
Edit: Ninja'd by rscaper10708k polys isn't really that much, there are much (poly) heavier birds out there.
If you really want to reduce the polycount ( my suggestion would be around 5k - 6k for this one),
take a look at the pic below, red circles show the areas where the same result can be achieved with a normal map.
I assume the areas with the red X are missiles? If so, remove them. You can visible missiles, all you need to do is to place a firepoint/ bank in PCS2 after conversion.
Can you upload a couple wireframe renders?
Edit2: might have been a good idea to actually post the link, eh?
