I like the first two. The stars on the second could be better but im not sure how. I have the same problem there. They come out just as white dots often hard to separate them from noise.
Not bad....tension in the first by including one full view of the tree line but not the other. The other two are great...you did chop the tree in #2. Maybe you have other shots to "un-chop" the treetop...or maybe reshoot. When I unintentionally chop things it makes me absolutely crazy!! So I sympathize with you #3 is an appealing art photo that I totally dig
