I like you first photo. However it has noise grains and a bit under exposed. The third photo is also a little underexposed.
For the second photo you should either zoom in more on the subject or add more depth to include more of the background. Zooming in more on the subject would be a better choice. There is also clolor fringing in the highlights.
All your photos seem a bit cool. As for the fourth image, I believe you placed the focus at the wrong point plus you might not have had enough depth. More of the centre leaf should be in focus to include the waterdroplet in the center.
The first photo is not sharp. Look at the log at 200%. It is fuzzy. also your horizon is not level. Your sky should be darkened to bring back details.
The second photo is not sharp.
The third photo has too much foreground and your subject is looking out of the photo. The shadows are too dark and the sky needs the details brought back.
The Subject in the third photo should be emphasized and properly cropped.
