How to edit like the sample photos

I am trying to edit my photos in Lightroom to mimic these sample photos that were the inspiration for my editing style, but after more than a week of tweaking and researching and watching YouTube, I cannot figure out what it is I'm doing that's preventing me from achieving the vision in my head, that's reflected on my reference board. Everyone says my photos look good, but they just don't have that dreamy element where the colors are true yet soft. I've attached my reference board (the style I want my photos to have) and two of my recently edited photos. Can someone please help?
