Disclaimer: I'm not a teacher, and you should read 0neye's guide to ship building.
Anyways, here's some problems with your ship:
1. You have reactors clustered together when you want them separate, both to more efficiently distribute power throughout the ship and so they don't chain-react and tear your ship apart.
2. No corridors or conveyers to efficiently move power around.
3. You don't actually need that many reactors, the reason things are running out of power is poor logistics.
4. The ship can't focus fire all of its weapons at its front, and what it can focus is underwhelming.
5. The reactors are poorly armored.
6. Too many reactors, the ship can run on fewer
7. The frontal compartments have no fire extinguishers.
8. You have too many missile factories or too few launchers (1 missile factor can support 2-3 launchers, as covered in 0neye's guide).
9. Ions violate the rule of combining equal strength beams.
10. Frontal prism is unshielded and exposed.
11. Factories, both bullet and missile, are not connected directly to their consumers.
12. The weapons on the inside have prohibitively small firing arcs.
13. The engine rooms it does have are underutilized and redundant (engine rooms don't stack, having multiple touching a thruster is a waste of engine room).
14. Command rooms in reactor blast radius
