I am not saying you shouldn't mention marks or anything.
I am just explaining my observation over years of punting and reading ARs. Not sure it's out of sympathy, privacy or other reason, I seldom see an AR mention WL's birth marks or scars. I have seen girl with big chest scar, and another one with big tummy scar. They both have multiple reviews and not one mentioned this.
I never ask why but I am certain oftentimes the reviewers just chose not to mention rather than didn't notice. Because it's a feature that is too obvious to ignore.
