I think having the hanger in there is a BIG mistake. Based on your size comparison, you could barely fit a fighter into the opening, let alone make the corner. On top of that, I'm not sure where you'd be able to fit the fighters in the ship. It barely seems to have enough space for a crew. If you chose to keep it this size, I have two suggestions for you... well, three if you count the no-fighterbay suggestion. First, if you want to be able to carry fighters with this thing, use external pylons and mount them in the space on the underside between the forward and aft hull. I'd say you should be able to fit six or so Perseus in that space. Secondly, add a small superstructure on top of the back end of the forward hull. I just think that it needs something there.
That's it for now.
