Conditions look super - good work getting out and about. Decent landscape images in the warmth indoors are hard to come by. Here's some critique for you which I hope you'll find useful.
#1: Not an awful lot going on here. The tree is a bit overpowering. You've got some lovely light along the top of the hedge on the left, I wonder if you could have used that more effectively. It looks like you have an exposure lightening halo around the tree but it could just be lighter cloud.
#2: This is very nice indeed and the best of the set. The wall is a clear interest point that brings you into the image. The little bridge/fence is lovely. Light is super. A "calendar" style shot. The contrails are the only downside. I think you could have stayed in this little area for a while and explored lots of different compositions as there's so much subject matter there.
#3: Nice light, nice curvy road, but a bit boring. Again, nice light on the hedges. Could you have got above them somehow and had a higher vantage point and used the hedge lines more effectively.
#4: You're getting some excellent light here. The trick is to combine it with a stonking composition with a definite subject or point of interest. This shot is lacking the latter unfortunately. Comparing it to #2 I think you can see what I mean. There's a lovely textured wall there and a nice gate which you might have been able to use. Otherwise it's a very nice view, and nothing wrong with that at all.
