This requires very deep customization of core comment system of woocommerce
and it's not part of regular support.

You can change theme's labels via translation

Hi, with my reviews system users can leave a comment, pros and cons. Pros and cons are optional but not the general comment. If users dont write anything on general comment they have an error message.

My questions:

- How custom comment field in order to write under the general comment section that this section is mandatory

- How to custom the error page that is not explaining enough what is the error

see images attached

Thanks you!
