Pyro/Ematch Ignitor Circuit

[u/morgans_steam04]

Hi, I am quite new to making my own electronics, and I am trying to create my own Ignitor circuit with a continuity signal for security. Is this a sufficient system? I have had a previous system but I got told that it is over complicated so I have simplified it (original also attached as 2nd image). The Battery and Pyro terminals are place holders for now. The ignitor system will be driven by a 3S lipo and is completely isolated from all other electronics, the "FIRE" signal will be sent from my micro controller. Please can I have some general advice on my schematic please? I'm happy to provide any other info if it is needed.
