Phili- one and two are difficult shots, seems you did fairly well! But three(above) seems to have an unusually high amount of background pixelization- what camera, lens, and ISO were you shooting with?
Thanks for sharing.

I have noticed though that I have a tendency to underexpose my shots a lot-trying to learn not to do that so that might explain that shot. Post processing artefacts if that's what they are called
