Hey look, the roosterpit glass looks quie tall and fragile.
Let's get something straight here; we're talking space age weaponry. If your ship lost its shield capability and got hit directly by starship munitions, it doesn't matter if the bridge is on the outside on the inside. You are going to lose half your ship in the explosion and be completely fried anyway. I would rather have a direct view of the battlefield via clean glass partition and binoculars in case of primary power failure than having my bridge defended by some extra bulk. And when I say "glass" I mean four-inch-thick battle grade transparasteel, of course.
Also, Mr. Hurricane, you said it's propelled by mass driver? You know that mass drivers are cannons, yes? Technically you could use a mass driver as a means of propulsion due to Newton's Laws of motion but it would be really impractical because 1) you'd have to constantly be carrying a supply of magnetic stuff to launch out the back of your ship and if you ran out you're dead in the water and 2) the forward force you'd get from that would be minuscule and definitely not FTL. But even then, those look like plasma engines, not mass drivers.
Rants aside; it's a neat looking ship. I'd like to see more on it though. The breaching system is cool but you should expand on it. Just ramming the enemy ship and blowing a hole in it with a breaching charge isn't going to create a stable entry point for your invasion forces to breach the hull. Perhaps a series of laser cutters would remove sections of the hull large enough for entry and simultaneously weld the edges of the entry point over to retain structural integrity?
Please take my criticisms in good faith. I say them only to see you improve on this design. I like the bridge, very detailed. Try changing the floor in the hallway to a lighter color; would make it seem less flat. Don't worry about making the bunks larger because military sleeping quarters aren't exactly luxury.
Aaaaand that's it! Good luck! I look forward to seeing your future work.
