Adjust width of Review popup

Dear Support Team,

I have a request which I am not sure if can be done easily.

At the moment, on the Reviews page (https://www.joywithjo.com/reviews/), when the user clicks on the popup, it looks great when there is an image attached to the review.

However, if there is no image, it looks a bit strange because the review popup takes up the same amount of space and the add to cart button is extremely long. Image here >> https://prnt.sc/quttqy

Is there any way to adjust the width of the review popup to maybe half the size when there is no image attached to a review? Or if you have any other better ideas to make it look better, I would be really happy to hear from you.

Thank you for your time in advance.
