Noob. Veterans, check my circuit please. Thanks.

I'd made a circuit for my very first saber. I has a NB sound board, 3.7V li-ion batter, speaker, 2.1mm jack wired to recharge and accept a kill-key, leds for crystal chamber, custom PLI, rebel LED. I would be very grateful if a veteran would look over my circuit diagram to double check my work. I've included the saber and its cutaway so that you can warn me against space concerns if there are any. Thanks again.




I used circuitlab.com to design the circuit. A link to the schematic can be found at: https://www.circuitlab.com/circuit/5e3f7u/sabercircuit/
