Nice one! I like the shuttlepods, though I must note that there's only room for 2 out of 4 crew members...
Anyways a few things to make it more combat effective:
- The point defense turrets should be cannon-cannon systems which will give them a much higher rate of fire
- You have an excess of damage beam modules on your secondary computer; adding more than the total number of missile tubes doesn't help. Balancing the number of modules will make the missiles stronger
- I would add some Defense and Power chambers to boost the power output and shield capacity
