I think that you have just tried to include too much. For example, you have a rock, but then a whole lot of other stuff out of focus. I am confused as to what you want me to look at.
The top photo has an interesting form in it. The little hanging down green thing with a droplet out front looks like it could be a little creature. Zoom in close, let it fill the screen. Omit the mass of out of focus stuff. Pick one specific subject and make your choice obvious. We do not need to recognize what it is, but it has to be interesting, something that grabs our interest and attention.
Black and whites work nicely if you have a lot of contrast. Keep trying!
