You could improve the composition of the flower and leaf photo. The fungi photo would benefit from more space around it; it is a bit too tightly framed, and the white balance could be adjusted slightly.
The composition of the drone photos seems to be fairly good.
Anyway, as a guide, read about composition from Adobe.
I like the fungi on a log. But the log has a slightly blue cast to it.
There is also slight clipping on the dark end of the histogram panel. Tweak the color balance & exposure settings just a tad. I think this could be a winner.
The flower image and the leaf are kind of "meh" from Adobe's standpoint. The composition of your photos are spot on to me, but they do start to lose sharpness and get "muddy" in some areas when viewed at 100%.
