Default SMPS PCB Layout Advice


I am starting my new SMPS Design, I have made the PCB for it (attached below).

Any advices or comments about it will be more than welcome.

One question about Cree page,
that distance in SMPS is required because Safety or it affects the circuit performance? and may damage the parts?

I paid attention to this point any way.

This PCB is not fully routed, any advices about the traces width also welcomed.

Thank you all.
