To avoid having to crop it quite so hard as xenoid's example, I tried this...
I healed out the worst culprits - the grey at the bottom of the wall & the post near the centre. I could have done more with the black panel & post towards the left but I was just doing a rough job as an example.
Then isolated the subject by blurring the background.
That let me crop far less harshly.
It's not perfect, but it took less than 5 minutes.
As regards the logic behind my choice - firstly to remove the worst distractions; the pillar/doorway hard left & the ugly grey buildings in background, which there's nothing you could do with except crop out. Then the grey stripe [gutter, pipe?]
I did, however, leave a hint of the shape contrast between the two opposing diagonals - the wall & the leaf, which I kind of liked once it became overall less distracting.
That X-shape could work. Had the lines in the wall been cleaner, I wouldn't even have blurred it out.
The more I looked at it after I'd posted it, I decided I'd punch a bit of colour into it too... [this from the last jpg as I'd already thrown the project away]
I also recropped at a slightly different aspect ratio, which I think pulls attention to the foreground better.
I reposted the original below so you can quickly A/B.
