The editing window seems to last for about 15 minutes. After that it’s still possible but it becomes a techie thing.
I took a quick peek at the two most interesting thumbs. Unfortunately the baby still attached is out of focus. Since you mention missed focus, I gather you already know about it.
The beautiful sunset was taken with a small aperture, so the sensor dirt shows. Sensor dirt is a scourge of digital. Get dirt in a film camera and it gets wound out with the frame as film is advanced, frequently washed off with the developer, once in a while it scratches a frame. With digital, even with the shaking filter assembly, dirt can be there in the same spot for hundreds of photos. You can heal it out but it gets to be a pain if you have to do a lot of photos. There are lots of videos on cleaning sensors, it is not difficult, just fiddly.
