Patrice,
That model is absolutely glorious in both implementations, yours and original. But no, I found nothing special. I was hoping for some normal maps but found nothing of importance. Probably I'll still try and use one of the original diffuse maps as a specular map but that isn't for sure. Anyway, that would need slightly brighter materials and a nearby sun or thermonuclear blast of a supernova to light the scene...
I also like your jets solution, it does look spectacular.
I found one minor spot of z-buffer fighting. (see the picture below) Probably not much to speak of but it's one of the front planes and it catches my eye as I'm zooming in on/out of the scene...
