We all try selective saturation the first time we learn to photo edit.
But then we stop.
So you did nothing wrong, yet.
#1 looks like a cool location. I like subjects that lead into the photo instead of away. Just how my mind works.
The goal will become making the photos speak for themselves without too much forced processing. Glad your out having fun and learning your styles and software.
Keep it up and save your stuff to look back on as you develop.
