This doesn't really explain how OIDC works, it just explains the flow of requests a user would see if they're setting up OIDC for authentication between two systems for the first time. But beyond that, I'd say in future blog posts it would look a bit more professional to use some kind of architecture diagram making software, rather than somebody's napkin drawings. It's a little more difficult than it needs to be deciphering these graphics. To be entirely honest, I'd settle for mspaint-level quality if none of the free diagram making tools out there catch your eye.
