Hey Kurt!
It's been a while, but you have come back with a bang!
Awesome work here! What a fun experience to do portraits under the Milky Way! The last 2 are my favorites.
Now I admit I obsess over little details.

so I will suggest that in #2 and 4 clone or crop out the little bits of trees that are poking in on the corner or edge. A full on tree makes for great framing like in #1. But just poking into a scene makes for a distraction. At least in my thinking,
