You're asking about things that might be done in pp?
Well, if it were mine, I'd clone out those two stray twigs in 3 which reach into your frame from above. You know which two I'm talking about?
And in Photo 2 I'd clone out that next tree which shows only just so little on the right.
I actually looked at Photo 1 for longer, taking in the straight verticals, which are really straight, which I like: the post, the main tree, the background trees. And suddenly, towards the top, that main tree breaks out of its straightness and divides ... I like that.
And I like the last, though it would have been nice to be able to follow that creek further into the pic and not have it end in a "cul-de-sac". Though I believe something very man-made would have shown in your frame had you stepped further to the left?
All in all I get the feeling that at this time of the year, the countryside "at home" is as bleak and dead (and waiting for spring to come) as it is around here...
