Ah that's really good then! If it is that low you don't even need to knock any off to round out your 90 degree angles. The main reason I suggest round out those 90 degree angles is because if you try to get any sort of bevelled edge in your normal map it tends leave a nasty seam. That's just something I found with my models.
Also how you have beveled the engines on the end of the fighters wings, looks quite nice. I'd like to see more of those beveled edges around the other parts. Imo it doesnt look as nice all sharp, but thats all personal preference
