Can you check if the stripboard conversion of this bufer circuit is correct?

The circuit:

The stripboard version:

Thanks for checking. When I was wacthing a video of how to make audio stripboard circuits, something was mentioned about that some inputs or outputs should not be placed to adjacent stripes. But I can't remember which ones were mentioned and I don't find the video any more. Which in or outputs could the video refer to?

Ideally, in any high-gain circuit, you want to try and avoid feedback between output and input by keeping them as far apart as possible. Similarly you should keep high-voltage AC (mains wiring, speakers, motor supplies) away from sensitive audio circuits. With stripboard this means avoiding having input and output on parallel adjacent tracks.

On your board it might be expedient to cut your output track immediately to the left of the two 10k resistors.

You are missing a power supply decoupling capacitor.
For this circuit, I would put a 10μF / 16V electrolytic capacitor between +9V and GND.
