Generally speaking nice work and it certainly has a vasudan feel to it, as for the fighter bay you can just as easily say it is two entry points for the same bay, lets face it the vasudans have launch tubes on both canon destroyer designs.
Criticism
- The armament as mentioned by others, to be honest if you halve the big beam count to 4-5 and use bgreen you have a nice heavy corvette (800 meters long or so), if you go down that route you dont want any intermediate sized beams just a good scattering of ant fighter weaponry (perhaps 4-5 AF type beams and some flack, you already have blobs which is good)
- The multi part turrets, something about them says terran to me, I think it is because the shape is very similar to what is used on many "terran" ships and not just from FS, not sure how to fix that though.
All in all, the shape is good, I love the "spine" and the bank of engines at the back. cant wait to see what you do with this
