Collimation looks good with the second pic....first pic showing slightly off but that's probably due to focuser shift moving off centre where there's more field curvature.
Note
I'm not a optics expert) but don't open Fresnel rings so much because It's harder to see any defects in optics with the light spread out to far.
Having said that I don't see any issue in the mirror.....looks good.
What you can do while waiting for a flattener is pull the main mirror cell out from the back and take some pressure off the mirror clips and re collimate.
