I think you should work on your focusing - as a rule, the objects that are very close to the camera should be in focus (or ones that are uncovered by other objects) and the background should be in view. Unless you have a very specific composition in mind (that's advanced).

So in your 3d pic the central plant should have definitely been in focus. And on the last picture nothing is actually in focus so that looks weird.

Focus is a main thing you should be refining. Good luck!
